My dad, who was a teacher, used to tell me that a teacher's goal should be for every one of their students to get an A. If that's your goal every day - to make every student or player learn - then it doesn't matter if you won last year or didn't win. When next year's team shows up, I try to help every player become as good as they can be.
The artist who aims at perfection in everything achieves it in nothing.
What moves those of genius, what inspires their work is not new ideas, but their obsession with the idea that what has already been said is still not enough.
