The purpose is to help, to prevent, to correct, to improve, rather than to punish. Criticism is not meant to punish, but rather to correct something that is preventing better results. The only goal is improvement.
John WoodenOne of my constant reminders was, "End practice on a happy note." I wanted the boys to want to come out to practice, and I wanted them to get a certain amount of pleasure out of basketball. It's a game. It should be fun. So I always tried to counterbalance any criticism in practice with a bit of praise. I wanted my players to feel that the worst punishment I could give them was to deny them the privilege of practicing. If they did not want to practice, I did not want them there.
