The more you learn, the more you realise that the world is not black and white. This contrasts strongly with the world we live in as children, where adults show us how to easily to put things into categories like “good”, “bad”, “right” and “wrong”.
One idea that I’ve heard is that there are two ways to learn things: education and experience (or book learning and doing).
Education is great because it builds your knowledge base from which you can act and change. But there comes a point when more education doesn’t make much of a difference – you won’t become great at driving just by reading road rules and your car’s manual.
