Should You Learn from Multiple Textbooks at the Same Time?
This lesson answers a common question among mathematics, physics, and engineering students:
Should I learn from multiple textbooks simultaneously?
The answer presented in this lesson is generally no. Students are encouraged to focus on mastering one textbook at a time rather than attempting to learn the same topic from many different sources simultaneously. :contentReference[oaicite:0]{index=0}
Topics vs Textbooks
One of the first distinctions made in the lesson is the difference between a topic and a textbook.
For example:
- Linear Algebra is a topic.
- Differential Equations is a topic.
- Electromagnetics is a topic.
However:
- David Lay’s Linear Algebra is a specific textbook.
- Gilbert Strang’s Linear Algebra is a specific textbook.
- Other authors often approach the same material differently.
While the overall subject may be similar, the notation, definitions, examples, organization, and problem solving strategies can vary considerably from one textbook to another. :contentReference[oaicite:1]{index=1}
A topic may be the same, but each textbook represents its own structured approach to learning that topic.
Why Students Want Multiple Textbooks
Many students believe that using numerous textbooks will accelerate learning.
Common motivations include:
- Finding easier explanations.
- Comparing different methods.
- Searching for shortcuts.
- Attempting to learn faster.
- Trying to cover more material at once.
The lesson argues that this often produces the opposite effect. Instead of creating mastery, students frequently create confusion by mixing definitions, notation, and methods from different sources. :contentReference[oaicite:2]{index=2}
The Language Analogy
The lesson compares textbook learning to language learning.
Suppose a student attempts to learn:
- Spanish.
- French.
- Japanese.
- Mandarin.
- German.
all at the same time.
While possible in theory, most learners would make faster progress by focusing on one language until a strong foundation is established.
The same principle applies to mathematics and science textbooks. :contentReference[oaicite:3]{index=3}
Following the Curriculum
The lesson strongly recommends that students use the textbook assigned by their course whenever possible.
Reasons include:
- The homework comes from that text.
- The notation comes from that text.
- The definitions come from that text.
- The examinations are based on that text.
- The instructor teaches from that text.
Using unrelated resources may introduce alternative techniques that do not align with the expectations of the course. :contentReference[oaicite:4]{index=4}
Master the textbook assigned to the course before searching for additional explanations elsewhere.
The Musical Instrument Analogy
Another analogy compares textbook learning to learning musical instruments.
A student attempting to learn:
- Piano.
- Violin.
- Trumpet.
- Guitar.
- Drums.
simultaneously will often progress more slowly than someone who focuses intensely on mastering a single instrument.
Likewise, mastering one textbook thoroughly often produces deeper understanding than casually reading many textbooks at once. :contentReference[oaicite:5]{index=5}
The Difficulty Principle
An interesting recommendation presented in the lesson is that students should not automatically choose the easiest textbook available.
Instead, students are encouraged to work through a book that challenges them.
Benefits include:
- Improved reading skills.
- Stronger mathematical communication.
- Better problem solving habits.
- Greater persistence.
- Long term intellectual growth.
The lesson argues that learning often occurs when students struggle productively with difficult material. :contentReference[oaicite:6]{index=6}
Building Expertise
A recurring theme throughout the lesson is that expertise takes time.
Students frequently underestimate:
- The depth of a subject.
- The amount of practice required.
- The value of repetition.
- The importance of foundational knowledge.
Rather than attempting to absorb information from many sources simultaneously, students are encouraged to build mastery gradually and systematically. :contentReference[oaicite:7]{index=7}
One Book at a Time
The overall recommendation of the lesson can be summarized as:
- Select a textbook.
- Read it carefully.
- Work the exercises.
- Master the material.
- Move to the next book afterward.
By completing one book thoroughly before moving to another, students develop a stronger foundation and a clearer understanding of the subject. :contentReference[oaicite:8]{index=8}
Choose one textbook. Master it. Then move on to the next one.
Final Message
This lesson argues that successful students focus on depth before breadth. While multiple textbooks can eventually become valuable resources, genuine understanding is usually built by mastering one carefully chosen text before expanding into additional sources. Patience, consistency, and focused study remain the foundation of long term success in mathematics, physics, engineering, and related fields. :contentReference[oaicite:9]{index=9}
Original Transcript
All right, you little humans. Oh, those humans. Let’s uh This is the afternoon delight. We’ll call this the afternoon delight. So, I usually do a podcast in the morning based off of a comment that I find. So, if you guys are whoever whoever’s comment is on top that is not a complete stupid idiot will get my attention. And uh
let’s see uh here let me uh let me organize these comments to something you can filter it contains questions. There we go. Uh
all right. So Shil
Din whatever says uh is it okay to learn from multiple textbooks simultaneously? Um
let me respond to your comment quick here. I am responding to your comment now. Period. The video will be uploaded in about an hour. Okay. So this is from she dialin sheel ded.
Is it okay to learn from multiple textbooks simultaneously? Well my child yes and no. Okay, let’s um let’s first understand something such that as linear algebra is a topic. David Lay’s linear algebra is the subject. Gilbert Strain’s linear linear algebra is the subject. Griffith’s electronamics is the subject that you’re studying. So, uh, when you’re learning a subject, it’s like a language. You’re learning
different dialects as well. There are different techniques in Gilbert Strain’s book and different definitions for similar problems, if not very much the same. But if you mix and match these techniques, they don’t work. Uh, another student had said something in a comment earlier about AI isn’t quite ready yet to do math. AI will never be ready to do math. What you guys don’t understand about AI is that it doesn’t matter how advanced AI is, period. It doesn’t matter how advanced it is at all. you still have to read every single line and cross-reference every single line with an accredited source, a legitimate source. So, it’ll I don’t foresee it ever being a useful tool for math because it will it even if it does it correctly, you still got to spend hours going through it one line at a time to verify that it is correct. You can’t just take it on blind faith that it is correct. You guys are confusing applying math in the in uh in everyday stuff with learning math. Huge difference. Best way to understand it is there is a difference in learning how to speak and how to write and applying it. Right now I am applying language and more or less slang. I’m not following any sort of MLA or APA guidelines or any sort of speech, the correct pronunciation. You got to dress a certain way and present yourself a certain way to pass my class. A lot of professors, they set their course up as an ode to their ego. If you can’t mimic me, I’m not going to pass you. And I’m like, but you’re wrong. And they’re like, it doesn’t matter. You’re in my course to mimic me. And and that’s something that you need to respect because the professor, as much as you disagree with them or their style or anything, they’re trying to help you see differently. And in order to see differently, you need to look through their eyes. They want to show you what they saw, which is what got them to where they are. You need to respect that. So when you ask, is it is it okay to learn from multiple textbooks? I ask you, why would you want to do that? It’s like it takes years to master a single language. So if you need to master Spanish and you’re trying to learn Spanish, French, Chinese, Japanese, also all the different dialects of India on top of Indian language, Mandarin, all the you know what you’re doing is you are embellishing your ego. Is that the right word? Embellishing for that. Hey Siri, define embellishing. Embellish means make something more attractive by the addition of decorative details or features. That may or may not be the correct word for that, but you’re you’re trying God. Jesus. What you’re doing when you’re learning from multiple textbooks is you’re not thinking like an intelligent person. You’re thinking like an egotistical person. You’re like, I want to know partial differential equations. I want to know regular differential equations. I want to know linear algebra. I want to know abstract algebra. I want to know modern algebra. I haven’t even started pre-calculus yet. These are the signs of a future failure. Somebody very capable but destined to fail. You guys are trying to get to the point that I’m at. 20 years of study. You’re trying to get to where I am in 20 days. It’s impossible. It’s not going to happen unless you can get that brain chip planted in your head or something. And if that’s what you’re holding out for, you might as well just kill yourself because you’re no longer going to be a human. Just giving up on life. Life is about the struggle. That’s what you’re here to experience and the rewards that come with it. If everything’s just handed to you, you might as well kill yourself because you’re a robot.
So, let’s let’s understand this. Okay. What you asked me is it is it okay to learn from multiple textbooks or should I just learn from one textbook. If you learn from multiple textbooks, you’re learning multiple subjects. You’re not learning anything. Each subject’s different. The questions that you solve in that book have to be solved with the rules in that book to get the right solution. Some of you kids have the worst arguments ever. You’re like, “That’s ridiculous. I can solve it with this book, too.” I go, “Yes, you can.” But you’ll have the wrong solution. What do you mean it comes out with the right answer? No. Coincidentally, it’s the right answer. And is it the right answer? How do you know it’s the right answer? Can you prove it’s the right answer? I I’ve seen a lot of kids um not directly but they’ve contacted me after they’ve watched like Gilbert Strange’s linear algebra and they use his techniques and his theorems and his his definitions on their homework and they hand in their homework and they get a failing grade and then they get mad because they’re like, “Professor Gilbert Strain, he wrote a book. He’s at MIT. He’s on YouTube. Why would I watch your lectures? This is MIT. It’s a better education. God, the the stupidest people in the world studying the most advanced topics in the world. Like, it’s amazing how stupid a person is that’s allowed into college that thinks that way. So, let’s paint a picture. You’re at University X studying David Lays linear algebra. And you think you’re with all your inexperience, your lack of education, this owed to your ego and arrogance and your brilliant mind, you think paying this professor in this university thousands of dollars to guide you through studying David Lays linear algebra. In your brilliant mind, you go to a social media platform to watch somebody else teach a different subject. Do you understand that you are in this college to study this subject and in your brilliance you go to a social media platform to study a different subject and then you turn in the methods from that subject in your subject. What you have done is you have started learning Spanish and you and your brilliant mind went on the internet to learn French and you turned in your homework for French in your Spanish course. It’s the exact same thing. There’s no difference at all. Period. If you think there is, do yourself a favor and change your major to business now before you get too deep into this and you fail completely.
So, you know, to go back to the beginning, you ask a question. Is it better to learn from one textbook or to learn from multiple textbooks? Each textbook’s a different subject. You guys don’t understand this because you haven’t been through enough of them yet. You don’t understand that the techniques in this book are not the same techniques as this book. The questions addressed in this book, the style, the the flow is very different than this book. They’re tackling the same questions. when you’re studying multivariable calculus, several variable calculus or vector calculus or multivariate calculus or advanced linear algebra, you’re going to solve the same problem 50 different ways.
So, so in essence, what you’re asking me is nothing. No, you can’t. Look, you you’re in college to study a very specific subject. That subject is contained within the book that is given to you. If you leave that book, you’re not studying that subject anymore. In your mind, you see, you think you’re studying linear algebra by sifting your nose through 20 different textbooks. All you’re doing is studying 20 different subjects. The problem that you’re going to encounter is in class, you can’t mix and match the techniques from this course and this course and apply it in the book that you’re using. You can’t do that. Period. There’s no arguments about it. You just can’t do that. And if you do do that, you’ll be asked to leave class and then you’ll have a little hissy fit like a little minstrating girl. That’s ridiculous. Gilbert Strains MIT. It’s a better school. I then Why don’t you go to that school? If that’s the school you want to learn at, why aren’t you there? Why why’d you go to this school? And you don’t understand. I’m paying this school so I can learn at M MIT and pretend and get a fake degree. You’re not getting It’s not a better education. It’s a different education. You guys, you’re not getting a better education watching an old man make mistakes on a chalkboard. He makes mistakes all the time. You copy those mistakes. Not only have you plagiarized incorrect data, but if you’re not using his book, you’ve copied the wrong data. Just been massive plagiarism. Dude, most of you guys that are trying to learn math or physics that come to my channel, that are in high school or are just starting college, you guys are not doing yourself a good service by looking at 50 different textbooks. You’re like, you’re like a a person that wants to be an athlete trying to learn 50 different sports. Choose one and master that, then move on to the next one. So, so to answer your question, no, it is not a good idea to study a topic from multiple different subjects. There are like a hundred linear algebra textbooks out there. They all essentially lead you to the same place or go a little bit further. It’s like an electric car versus a gas car versus a good highway fuel car or whatever mileage or whatever. It It’s a vehicle that gets you from point A to point B. Some go a little further than the other ones. Some are better in this situation. Some are better in this situation. But on the outside looking in, they’re the same thing. There’s a door. You open the door. You sit in the car and it takes you somewhere. That’s what you guys think the books are. You think they’re all the same. But when you get inside the vehicle and you see how the motor works, is it gas? Is it electric? Does it run on hatred? Then you realize that you’re to to learn how to build a Tesla. You would not want to learn how to build a Ford and a Honda and a Mercedes all at the same time. You would learn how to build a Tesla so that a company can hire you to build a Tesla. And you you go to this college to learn how to study these subjects. In the order that you’re studying them for the degree that you’re getting, a company might be interested in hiring you to build that Tesla. If you stretch yourself through thousand different books from a thousand different schools, you’re going to have a thousand half-assed useless skills that no one is going to hire you to do. So you guys, the the real the real issue here is your ego. I hate that word. It’s the only word you guys understand because you don’t understand English because you you all still think the definition of insanity is doing the same thing over and over. It’s like you think that’s the definition of insanity. No one’s going to trust anything that you say or think because you don’t know what you’re saying when you talk. It’s your ego. The real question that we’re dealing with here is your ego. You want to be Iron Man. You watched a movie. You saw a fictitious character that seemingly knows everything. Or you look at someone like Nicola Tesla, a depressed, lonely, miserable old man that could not function in society and was beaten by everybody abusively, intellectually because he was trying to help. No good deed goes unpunished. Crap. Do you really want to be a celibate old man that gets no credit for the work he does until a hundred years after he’s dead? That’s not something to aspire to be. Go to college. Follow the curriculum. Follow the code of conduct. Follow the syllabus. Master one in book at a time. Stop trying to be Iron Man. It’ll take you 10 years to understand a single subject that you study. You do linear algebra, differential equations, calculus, physics, any of those. It will take you 10 years to understand a single one of those. When you’re in college, you’re being walked down a track of interconnecting links. When you switch colleges, those links are broken and you have to backtrack and start over. You can’t it’s it’s difficult to take calculus at this college and then calculus 2 at this college. They go down different paths. Even if they’re using the same book, the professors will take you down different paths. My argument is not an argument. It’s a clarity. I’m clarifying. You think that linear algebra is the subject and all of the books address the same thing and that this professor does it better than this professor because they’re spoon feeding you the solution easier than this professor. The best textbook to use is the one that’s the most difficult for you to read. You master that one. That’s the best textbook to use. The one that’s the easiest to read is the one you should throw in the trash because a future employer does not want to hire somebody based on their ability to choose the easiest path. They want to hire somebody based on their ability to choose the most efficient path. Do you understand? The easiest path is not the most efficient. To become more efficient, you must become an expert at overcoming obstacle. Your issue is your ego. I had the same problem. Don’t take it personally. Right? When I was 20 years ago, I bought every single textbook, every book there was. I’m like, I thought if I surrounded myself by a whole bunch of stuff that take me 500 years to learn that through osmosis, it would just absorb into my head.
It ain’t work that way, kid. And all the AI in the world is not going to help you learn nothing. So do yourself a favor and find out what book they plan on using in the course you’re going to take. One course at a time. Mathematics is different than the other courses you got to take in college. Mathematics you do one course at a time in the order that they are delivered. Do yourself a favor and find the book that they’re going to use for that course and master that book and only that book. When you master that book, then you’ll be able to read any algebra book. So, this is the this is the answer to your problem. You’ve got 10 different algebra or linear algebra or differential equations textbooks that you don’t know how to read any of them. If you master one of those books, then you’ll be able to read all of them. That’s what I show you with Plem Academy in the mentorship sessions. I take random books I’ve never seen before that I’ve never used. I take a random problem from somewhere in the book, middle, end, beginning, and then I use the book and only the book to create a streamlined algorithm that does spoon feed the solution. That’s what you guys are supposed to do. Decipher, the hieroglyphs into a formula that you can memorize and deliver on the exam. And if you do it the way I show you how to do it, you’ll me you’ll remember all of that stuff when the exam comes naturally. You’ll just be able to apply it naturally. If you do it the way I show you how to do it, it will be downloaded into your head and you can extract it on demand and apply it quickly, efficiently on the exam. So to sum up, young lady boy, she Daniel, whatever, choose one book and master that book. Choose the book that’s the most difficult for you to read. Not some super advanced book. I’m talking like you got you got Sullivan algebra versus Steuart algebra versus this algebra versus this person’s algebra. Choose one and choose the one that your course is going to use or choose the one that is most difficult for you to read and master that one. When you begin the process of actually mastering one book at a time, what you’ll understand what you what you’ll learn is that the first few chapters will take you a hundred times longer to understand than the rest of the chapters. The first page could take you 20 hours, but a 100 pages from now will take you 20 seconds. If you if you do the work at the beginning, you get over that hump, then it’s very easy. Then the next book will hump will be a little bit lower and then it’s and then a little bit lower and a little bit lower and a little bit lower. These textbooks are are weapons. You have to know how to use these weapons. When you’re in the workforce, you’re not going to just like you’re going to come across a linear algebra problem and you’re going to be like what you need to know on how to solve that problem. The techniques come from this book. They’re not in that book. They never addressed the situation in that book. So, you got to go to this book for that situation.
You’re going to want to be able to read these books on demand when that happens. So, put your ego in the trash, better yet, in the toilet and flush. Get your ego out of here. Humility. No good scientist is egotistical. And yet people I said scientists a lot of people are like phys physics professors they’re so eager. Yes. Do you know why the average math physics engineering computer science professor accomplished nothing? They studied for years and years and years went to graduate school. Did an original contribution to something that has no application that no one will ever read or hear about. And now they’re a professor. They went to school. They were told how smart they were. They went to college. They were told how smart they were. They went to grad school. They were told how smart they are. They graduated. They were told how smart they are. Then they get a job as a professor and are told how smart they are. Now they’re in charge of a group of people and they are the smartest person in the room. They’re God. They’ve never worked in the real world. They never experienced interaction in the real world. They never really accomplished anything. But boy are they accomplished. Do they know everything? And yes, these people are arrogant, egotistical people. Many, many of them are. The ones who have actually done great accomplishments, great contributions to the scientific world. They’re humbled. They usually have a lot of humility. They’re not arrogant. They don’t think they’re right about anything because any real scientist knows that you’re not right about anything. You can’t be. It’s impossible to be right about anything. All you can do is do studies that suggest outcomes or prove something under a set of rules. Nothing. You can’t be right about anything. If you’re having arguments with people and you think you’re right about something, you’re effectively an idiot, a complete freaking [ ] That’s why I can’t stand you snot-nosed little pricks that leave comments on here. You guys are arguing as if you know something, as if you’re right about something. You can’t be right about anything. And I know some of you are thinking that’s just that’s just not true. I’m right about that. I’m right about that, Mom. 2%. Chocolate chips. Ohoy. Look, put your put your mother ego in the trash and toss it out. Okay, humble yourself. Become humilized. Is that even a word? Look it up. Humility. Okay, you’re not right about nothing. You don’t know nothing. You’re never going to know anything. What you’re going to experience on the other side of the fence when you get over here with me is that the 10, 20, 30 years of studying math and physics, all it did was separate you from everybody else. That can be a good thing. It can be a bad thing. But what it’s going to do is it’s not going to elevate you in society. It’s going to separate you. Everybody else that does not have an education at your level is going to think you’re a pompous [ ] And the other people that have an education at your level are either going to respect you or disrespect you. It depends on if you’re egotistical prick or not. All the great scientists that I have met in my years. People I mean one of the one of the professors at UT Dallas won the Nobel Prize when I was there. the scientists that I knew, the physicists, the mathematicians, the engineers, the professors, the me the ones I I was put through a ring of, you know, some of them were arrogant little pricks and some of them were not. And the ones that weren’t, they they were the they had the greatest accomplishments. The ones that were civil and humbled, they had the greatest accomplishments. The ones that did nothing, they walk around acting like they know everything. I mean, they did something. They made an original contribution, but it it it’s like who cares? What is it? It’s a 500page dissertation on how the interloops of quantum mechanical interdimensional space operate under algebraic structure in modern uh relation to a super complex uh function. Uh it would take anybody with any education 10 years to understand their work unless they were equally in the same field. And it’s like, okay, so 500 years from now when super robots are building things, they’ll look at the work that this professor did and they’ll honor the robots will honor this professor 10 years ago, the professional student. My point is is that you most likely want to learn from a lot of books because you’re not worried about learning the subject. You’re worried about other people thinking you’re so much smarter than them. I’m so much better than you. I’m superior. I spent 20 years leeching off of government money, making an original contribution to a subject that will never be read. I’m so great. People who think like that, you know, most of the time you fail, but some of you do get through. And I I know you, one of you are my friends. This guy, he just is a gelatinous blob of ego. Sits around, has nothing, has done nothing for anybody. He’s going nowhere. He’s just a gelatinous ball of ego. He thinks he knows everything about everything. And I know what some of you are thinking. Isn’t it you? No, I’m wrong about everything all the time. That’s why I’m constantly checking definitions, citing sources, sending you to accredited places, telling you to read the book, to get away from garbage things like AI. To stop having pathetic, worthless arguments with complete strangers through the comments on YouTube. It’s pathetic. I mean, it’s absolutely pathetic.
So as your doctor, I prescribe you logic. Choose one subject, i.e. one textbook. Go look up what I do. Ee, I do. E dot means the Latin and what it means in English versus E. G dot. Go look it up. Have a source. This the reference according to this source. I do. E dot means this. Have a source. Begin professionalism now or forever hold your diploma. Choose one subject and master that subject. Then the other subjects will be quite easy. Don’t confuse subject with different topic. Linear algebra is the topic. David Lei linear algebra is the subject. Gilbert strain linear algebra is the subject. Choose one subject and master it. If you do not have a book to use, choose the one that’s the most difficult to learn from. And not some, like I said earlier, not some stupid advanced book, a regular book. Some people don’t like Gilbert Strain’s book because there’s not enough fancy colors and pictures in it. That’s probably the book you should use. Then David Lay’s book is a little bit more spoon feeding you information. Gilbert Strain’s book’s a little bit more you got to think. You got to use your brain. However, they’re two different sciences. David Lelay is more like I mean they’re both engineering application stuff but they’re different worlds. They’re two different subjects. Choose one and master that one. If you want to learn more about linear algebra then choose another linear linear algebra book and master that one. The only reason I I know so much about linear algebra is because I tutored it every semester for 15 years through hundreds of students from hundreds of different books or probably like 20 different textbooks. Hundreds of students hundreds hundreds of schools. Hundreds of curriculums. I was exposed to many, many, many, many different forms. And I’d always have students come to me and bring me their problems. I’m like, “What textbook are you using?” And they’re like, “We don’t have a textbook.” And I go, I go, “Yes, you do. You can’t do this without a freaking textbook. You need the freaking textbook.” Well, the the professor didn’t give us one. I’m like, “All right, kid. Give me your syllabus. I don’t have my syllabus.” I mean, this is that person like, “You’re at linear algebra. You you have they don’t even have the syllabus.” And this is when I say, “Look, I I can tutor you through this. You’re going to fail, though. It’s a waste of your life. Well, I I’ll figure it out. I’ll No. God, you guys keep cheating and cheating and cheating. You can’t cheat through these degrees. If you cheat with AI or Khan Academy and you pass the course, congratulations. You have a useless semester under your belt that will cause you to fail when the links snap and break apart. So, they open up the syllabus and what does it say? Usually David Lelay. It’s usually David Lay’s book at most of these places. Oh, I guess there is a book. Yeah, dude. These questions are bounded by rules. Those rules are in the book. They’re not made up. They’re not imaginary. They’re not coming from nowhere. They come from the mothering textbook that you are using in your class. So, take that for what you will. Slap yourself in the face. Give me your sister’s phone number. Have your sister give me a call. She cute. Make sure she’s of legal age. Guys, these questions are solved with the rules from the book they come from. Don’t make your life more difficult than it already is. It’s very difficult to master a textbook. Don’t try to master 10 textbooks when it takes you 10 years to master one. It’s you you don’t what you’re asking me. You’re like, “Is it easier to learn how to play uh a Nirvana song on the piano, the guitar, the violin, the flute, all these different instruments at the same time? Or is it easier to learn how to play the song with one instrument?” That is literally what you’re asking me. Literally, you’re like, “Is it easier to learn how to play music by playing 50 different instruments at once, or should I focus on playing one instrument?” Think about that logically because that’s the exact same comparison. Each subject’s a different musical instrument. The violin looks very similar to a guitar. It’s got strings. You can pluck them. Very different tool. It outputs music. Linear algebra outputs solutions. Very different tools. You’re learning how to use different tools and your school chooses those tools back to back to go together.
Some of you kids are just hopeless. Just hopeless. So, but to answer your question, dude, choose one book. Master it. Preferably the book that you’re going to use at the school you plan to go to or the school you’re at. If you’re not at school, choose one book. Choose the one that is the most difficult for you to learn from and master that book. I if you can’t do that, leave science, leave math, leave physics. You’re wasting your time. You’re wasting your money. You’re wasting your emotional investments. You’re just going to fail. You can’t learn 50 different musical instruments at once. You master one and then move on to the next one. If you try to master It takes 10 years to master one instrument. If you try to master 10 instruments at once, it’s going to take you a thousand years. I know you’re like, “There’ll be a hundred years.” No, because when you’re mixing and matching, you’re losing you’re losing the connection, the linking connection that of practice with one, you practice the piano this week, then the guitar that week, then you’ve lost all the skill from the piano. When you come back to it two months from now, after you done the 10 other instruments, you lost all your skills. You choose one instrument and master it the same. Does this one do anything? The same with math and physics. Choose one book, master that book, understand one book, master that book, and then move on to the next subject. All right, that’s the afternoon delight. If you’re a lucky contestant, not a douchebag, when I scroll through the comments on my cellular device, I will find a comment worth addressing and I will make a podcast in the morning and the evening, twice a day. the morning delight, the afternoon delight. I take comments worth discussing from people that are not douchebags. If you’re a douchebag, I usually report you for being a douchebag and ban you from my channel. And uh if you ask a question nicely and try to keep it one sentence or less, I’m more inclined to look at your comment if it’s a less than one sentence. You guys put paragraphs and paragraphs of stuff on there like I actually care. I got thousands of people that do that. That’s not going to help you stand whining and whining and complaining complaining and giving me your life story is not going to help me read your your content. Just so you guys know, okay? One sentence or less much more inclined to read it. Okay, that being said, your ego today, flush it down the toilet. Get used to saying, “I don’t know the answer to that.” That’s step one in your journey of becoming a proper scientist, children. All right. All right. See you guys in the nightly upset. Ooh, it’s Tuesday.
