Learning to Learn

Something from Andrej Karpathy on learning that stuck with me [0]:<p>&gt; Learning is not supposed to be fun. It doesn&#x27;t have to be actively not fun either, but the primary feeling should be that of effort. It should look a lot less like that &quot;10 minute full body&quot; workout from your local digital media creator and a lot more like a serious session at the gym. You want the mental equivalent of sweating. It&#x27;s not that the quickie doesn&#x27;t do anything, it&#x27;s just that it is wildly suboptimal if you actually care to learn.<p>[0] <a href="https:&#x2F;&#x2F;x.com&#x2F;karpathy&#x2F;status&#x2F;1756380066580455557?lang=en" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;karpathy&#x2F;status&#x2F;1756380066580455557?lang=en</a>

A big hole in this article is that you need to find the very best learning resource there is. This is a must.<p>Eg: For RL it would be Barto&amp;Sutton book.<p>Sometimes the best source is not intuitive. Eg: The best way to become a safe driver is to go to performance drivign school - its a bit expensive but they tell you how to sit and stay alert in a car which I have never seen outside of these schools.<p>One of my most common things nowadays is to ask ChatGPT is to ask to build a curriculum. Creating and understanding what a great curriculum looks like is 20% of the work of understanding a field.<p>You can LEARN ANYTHING now if you have the time and inclination and elbow grease. Truly nothing is beyond your grasp - NOTHING. Its a magical time.<p>I&#x27;m actually building a tool that will do all this for you and get you started down the learning path faster than what we have now.<p>And for the curious - the best way to learn medicine is not a textbook. There are solutions out there like Skethcy which work much better for anatomy.<p>My own learning project - learn Medicine &quot;on the side&quot;. It seems ludcirous that we give up the keys to our health to doctors just so we don&#x27;t have to learn 2 years of courses. Am going to fix that!

Posts like this that talk about learning &quot;efficiency&quot; always come off as soulless and dystopian to me. I think learning should be fun and that fun learning is the most effective---that&#x27;s the only thing I optimize for and I certainly don&#x27;t think about efficiency percentages. What a drag that would be.

This is something I have personally struggled with, so I wish the author elaborated more. If you are a novice, how do you quickly identify what the foundational knowledge is? How do you know what makes you an expert and not an &quot;expert beginner&quot; as the author says to the extent that you can build a personal curriculum about it?

I&#x27;ve been wanting to try this approach for learning a language.<p>In English for example, learning the 800 most common words, you can understand 75% of the language: <a href="https:&#x2F;&#x2F;www.bbc.com&#x2F;news&#x2F;world-44569277" rel="nofollow">https:&#x2F;&#x2F;www.bbc.com&#x2F;news&#x2F;world-44569277</a>.<p>I&#x27;d love to start fresh on a new language, take 800 new words, try to learn 10 a day, and see where I get after 3 months. Can I really understand 75% of text if I have perfect recall of those 800 words?

Pareto distributions are everywhere, and most learning ends up being one. Recently encountered this while getting into weight training for hypertrophy. The core is good form, diet, and progressive overload. Other than that, learning the basis of a specific exercise is something you can pick up as you expand.<p>It&#x27;s so similar to most of the things I&#x27;ve specifically sought to learn as an adult. You get so much bang for your buck, time-wise, when learning something new. The best part is when you don&#x27;t even need to dig deep past that foundational 80% and you can become pretty knowledgeable about something in a very reasonable amount of time.

I cannot recommend reading A Mathematician&#x27;s Apology enough. It was written by GH Hardy and I think it&#x27;s one of the best non-math texts out there to understand how a mathematician&#x27;s brain works.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;A_Mathematician%27s_Apology" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;A_Mathematician%27s_Apology</a><p>Fairly short and beautifully written.

Contra to a lot of what&#x27;s being said in this thread, I think a lot of smart people get stuck in the trap of overvaluing quality of input relative to quantity of input. Put another way: the bitter lesson applies to the AI inside your skull too.

The initial cram is an interesting concept. If you insert new things to learn at a constant rate, the repetition burden grows logarithmically. Assuming you have some fixed amount of time you can devote everyday optimally your repetition burden should be constant. So the solution is making new things to learn not constant, but front loading a lot of it.

I agree with the blog post that learning how to learn is an important skill. But the post offers very little beyond a few tips on how to actually achieve that. For people interested in actually learning how to learn I&#x27;d recommend the book &quot;Make It Stick: The Science of Successful Learning&quot;, which offers a lot of details on this topic based on actual scientific research.

Identifying what the foundational knowledge is isn&#x27;t easy for an absolute begginer.<p>Building an efficient path to expertise is hard for a beginner.<p>I think the fastest way to learn is asking an expert to build a learning path for you, starting from what you know and what you don&#x27;t know.

I will have to disagree with the author on specifics (but agree on the broad premise)<p>it is not what the foundational knowledge &quot;is&quot; - but &quot;how&quot; the foundational knowledge is &quot;unpacked&quot; by each person from the first principles.<p>this was articulated by Descartes in &quot;Rules for the direction of the mind&quot; which remains sadly unread and forgotten.<p>the difference between the 2 approaches is that the author&#x27;s approach does not clearly delineate what is meant by &quot;learning&quot;. In fact, it could even encourage rote-learning of the foundational material. Descartes outlines an alternative.<p>An interesting anecdote about Descartes is that he &quot;unlearnt&quot; everything he knew early in life, and attempted to &quot;rebuild&quot; his knowledge. Few of us have the luxury to do that.<p>link: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Rules_for_the_Direction_of_the_Mind" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Rules_for_the_Direction_of_the...</a>

IMO, how to learn depends greatly on why to learn and what constraints do you have.<p>If you need to pass an exam, obtain a certificate, etc. you will need a different approach than if you are just curious about a subject and explore what it is about.<p>There are commonalities, however. Much of the advice on deliberate practice (From the book Peak Performance) is valid even if you don&#x27;t try to be a top expert.

&gt;What’s something you’ve learned that you believe gives you an edge - something that you’re almost surprised more people don’t know about?<p>I don&#x27;t know if it&#x27;s just me but I would not be stoked to be asked this question during an interview. During interviews you&#x27;re implicitly trying to differentiate yourself from others vying for the position. You usually do this by talking about your experience in different ways. I find it annoying when the interviewer explicitly asks you to differentiate yourself from others vying for the position. In part it annoys me because I think that should be the job of the interviewer to determine based on how I&#x27;ve answered their concrete questions about my experience. But also explicit questions like this one give such an opportunity for bs that I do not think they give a lot of signal. I guess I could be wrong though and don&#x27;t spend enough time thinking about what makes me better than other people.

Part of growing up, going to school and then college, and then through life is that you learn how to learn. Everyone develops their strategies to learn.<p>Some think that the strategy they found for themselves is great, and they start preaching it. Like this person here. But it&#x27;s an illusion. Maybe it even has a name. This particular strategy doesn&#x27;t sound bad, but there are so many types of people out there, and it&#x27;s certain that for many, if not most, other strategies fit better.<p>It&#x27;s like trying to teach someone how to run. Advice like keep your back straight, or land on your toes, etc. In the end, running is the best teacher. Just go ahead and run, and your body will figure out how to keep the back straight.

I think the best learning resource for something is being really interested in it.

&gt; Very quickly identify what the foundational knowledge is.<p>This seems to be the most important part but also has the hidden and problematic dependency of... already knowing (i.e. already having learned) what the foundational stuff is?

For me, there’s always an early social element to learning: trying to figure out who the experts are; getting them to point you toward the best resources; and if you’re lucky, bouncing your mental models off them to be corrected. A good LLM can take you part of the way on many subjects, which removes some of the initial friction.<p>Not every field is like that though.<p>Some problems are wicked and new, lots of knowledge is basically enacted more than known, and the solutions one seeks often require several disciplines.

I dont think it&#x27;s going to be that important. Different people have different learning styles but also vastly different capacities making this really difficult to research accurately. People claim to find the secret sauce from time to time. They&#x27;re most likely wrong.

I have a related question: Is learning interlinked with writing?<p>PG tweeted:-<p><pre><code> You can&#x27;t replace reading with other sources of information like videos, because you need to read in order to write well, and you need to write in order to think well.</code></pre>

The biggest challenge in learning is identifying gaps in your knowledge. Dunning-Kruger is a real thing and you want to avoid that.<p>Part of learning to learn, is learning how to identify the things you don&#x27;t know. Then learning how to structure your &#x27;personal curriculum&#x27; them in a rational way - you don&#x27;t <i>need</i> to know everything up front to be effective.

Learning depends on the environment and whether it is pursued in an auto-didactic sense (Even for a job, say) or whether you are learning for an exam&#x2F;part of a cohort.<p>It&#x27;s not wrong to say Curriculum does not matter. But the level of curriculum is also something that needs to adjust to your current level and related fields you have knowledge within, to prevent you becoming overwhelmed.<p>Most people stop learning being motivation dries up as Test Anxiety rises to the point where they are at a &quot;low-performance&quot; place in the eustress curve. A few days there and people pause until it becomes urgent. A lot of this is a lack of momentum, but also not dedicating or having access to judgements of learning about your own progress.<p>In other words, if you judge your learning at all, it helps you manage.<p>There is a natural tradeoff between the flow-state of &quot;just one flashcard with one information principle at a time, endlessly&quot; and the longer term state influencing your time in flow-state of &quot;am I progressing, what don&#x27;t I know, how do I feel about my learning and mistakes?&quot;<p>Think about learning databases, or CSS. When did you really takeoff? Probably A) Practically copying others examples (existing queries ran in PhpMyAdmin, or codepen code) And then later B) Once you overcame a big mistake and saw progress - suddenly what &quot;Display&quot; did clicked for you, and you saw how useful it could be to use the &quot;fixed&quot; option, it unlocked your understanding of the items in A and confirmed or disconfirmed your understanding of how it works.<p>Again it all depends. Self-motivated learning, even for a job, is easier to work with than compulsory learning. Because there, you don&#x27;t even have the motivation to gaze up to the horizon and gather any excitement or understanding for what the learning might later lead to. It doesn&#x27;t feel like a path, it feels like a brick wall. In this regard, a list of subjects is somewhat skin to someone stacking bricks, rather than elucidating a path. Overwhelming anxiety while learning is a real thing. The context really matters as to whether this approach is always the wisest.
