" He wasn't tough. A tough man has to win and lose. He has to come up after being knocked down, he has to have taken a few beatings, and know what it means to win the hard way. Anybody, he said dryly, can knock a man down. When you've been knocked down at least three times yourself, and then got up and floored the other man, then you can figure you're a tough hombre. "

― Louis L'Amour
