That you can't get by on intelligence. School had not prepared me for actually learning.

Best way to learn is by mistakes. Made a lot of them and it really sticks.

My brother was also too intelligent for school to be a challenge. It's not that you won't make mistakes, it's just that you postpone them. The earlier you make them, the better you will be prepared.

School blames mistakes and failures, so it basically teaches you how to avoid them and not to learn from them. So you spend years of your life learning tricks and “recipes” for known problems. But that’s not how it works. We learn to walk by falling and with encouragement by our parents. I would like to find a teacher that encourage you instead of blaming you. They are few and generally considered rebellious by others.
