You can learn anything

Any subject can be learned with some practice and patience. Some subjects may appear harder because of the speed at which they are taught.

To fix this problem, you may need to put in more work. If you can't see everything at once, it just means you need to practice more of the pieces, so your mind does not have to juggle so many ideas simultaneously.

Problem Solving


Because we can increase our working memory within a subject, we can create new chunks and master very complicated ideas. The perceived difficulty is often the way subjects are taught. Only the smarter students will remain, the higher you go in maths or science. This leads teachers to skip over "trivial" steps, leading you feeling like you can't master it.

Solutions are for teachers to slow down the class or for the student to slow down the class using, for example, the Feynman Technique.

Being smart changes how you learn things

Intelligence is likely associated with a better generalised working memory.

A working memory is the ability to hold multiple ideas in your head at the same time. Those who are smarter have a bigger capacity to hold multiple ideas.

Some subjects feel like they require more intelligence. If understanding an idea requires you to take different ideas into account, it may be more challenging to keep track with a lower working memory. e.g. mathematical proofs.

Conversely, if a subject requires a large volume of memory, but each fact or idea is separate, it may require lots of practice and less working memory. E.g. history or law.

Intelligence is partly heritable, but there are ways to improve it in a general capacity. The best way to improve your working memory is to simply learn a lot. Learning creates chunks, which allows you to deal with more complex ideas.

The downside of learning is that it tends to be narrow, while intelligence is general.

Learning how to learn is a meta-skill. It is a critical skill for everyone who needs to pick up and master new concepts frequently.

Understanding what is learning and how our memory works will help you understand why certain techniques work and how to use and adapt the techniques to your advantage.



The Feynman Technique

Richard Feynman understood the difference between:

  • knowing something and
  • knowing the name of something

He created a formula for learning that ensured he understood something better than everyone else.

How to build general skills

General skills not only help you with a narrow problem but can be used repeatedly to solve other problems.

But building general skills can be challenging because it is built from many specific ones. If you're prepared to do the work, you can find better ways to learn that can make breadth possible.
