Wooden: On Doing Your Best

"A coach can only do his best, nothing more, but he does owe that, not only to himself, but to the people who employ him and to the youngsters under his supervision. If you truly do your best, and only you will really know, then you are successful and the actual score is immaterial whether it was favorable or unfavorable. However, when you fail to do your best, you have failed, even thought the score might been to your liking.

This does not mean that you should not coach to win. You must teach your players to play to win and do everything in your power that is ethical and honest to win.

I am rather thoroughly convinced that those who have the self-satisfaction of knowing they have done their best will also be on the most desirable end of the score as much, and perhaps more, than their natural ability might indicate."
