6.4.0 Create = teach or write or both
6.4.1 Create: Teach
6.4.2 Create: Write
The basic theme is that whenever you cannot understand something, you should try to create that thing.
How to create?
Write. Write as if you are explaining the materials to someone else.
As physicist Gerar’td Hooft advised, when reading a physics textbook “… imagine how you would write those texts in a smarter way.”
Why is that you can understand a thing when you re-write your textbook?
It is because whenever you write, you have to translate the materials into your own language.
You are CREATING your OWN knowledge.
