“But when they lose a chess game, they know that they have no one to blame but themselves. They had everything they needed to win, and they lost. If that happens to you once, you can usually find some excuse, or just never think about it again. When it's part of your life, when it happens to you every single weekend, you have to find a way to separate yourself from your mistakes or your losses. I try to teach my students that losing is something you do, not something you are.”
