“A good player who loses at chess is genuinely convinced hat he has lost because of a mistake, and he looks for this mistake in the beginning of his game, but forgets that there were also mistakes at ever step in the course of the game, that none of his moves was perfect. The mistake he pays attention to is conspicuous only because his opponent took advantage of it.”

“The coach who goes home and doesn't think about the game he just lost is bound to repeat his mistakes.”

“He doesn't even look at her because there is too much there, and he's afraid. She is his first child, his favorite, every mistake he ever made.”

“The chess-board is the world; the pieces are the phenomena of the universe; the rules of the game are what we call the laws of Nature. The player on the other side is hidden from us. We know that his play is always fair, and patient. But also we know, to our cost, that he never overlooks a mistake, or makes the smallest allowance for ignorance.”

“He didn’t ask for mistake-free games. He didn’t demand that his players never lose. He asked for full preparation and full effort from them. “Did I win? Did I lose? Those are the wrong questions. The correct question is: Did I make my best effort?” If so, he says, “You may be outscored but you will never lose.”

“No man chooses evil because it is evil; he only mistakes it for happiness, the good he seeks.”
