difficulty in retrieving the correct information—even when the difficulty is caused by the information not being there—can prime you to remember information better later.

Feynman didn’t master things by following along with other people’s results. Instead, it was by the process of mentally trying to re-create those results

most people learn abstract, general rules only after being exposed to many concrete examples. It’s not possible to simply present a general principle and expect that you can apply it to concrete situations.

when you lack knowledge about a subject, you also tend to lack the ability to assess your own abilities. It is true that the more you learn about a subject, the more questions arise.

to avoid asking questions in the vain attempt to appear knowledgeable, has considerable costs.

method is quite simple:
Write down the concept or problem you want to understand at the top of a piece of paper.
In the space below, explain the idea as if you had to teach it to someone else.
If it’s a concept, ask yourself how you would convey the idea to someone who has never heard of it before.
If it’s a problem, explain how to solve it and—crucially—why that solution procedure makes sense to you.
When you get stuck, meaning your understanding fails to provide a clear answer, go back

this approach is when you don’t understand something at all. In this case, the easiest way is to do it with the book in hand and go back and forth between your explanation and the one in the book.

very important to go through the problem step by step alongside the explanation you generate, rather than simply summarizing it

to focus on generating illustrative examples, analogies, or visualizations that would make the idea comprehensible to someone who has learned far less than you have. Imagine that instead of trying to teach the idea, you are being paid to write a magazine article explaining the idea

voltage is to the electrical force as height is to the gravitational force.
