Praise

I dreamed of a coach trying to teach kids to pitch a baseball. He would walk behind them as they threw clapping and encouraging them each time they made a mistake, but once they got the hang of it the clapping stopped. One child puzzled over why the coach stopped praising their efforts, once they got it right. The realization was this -

Praise is only necessary until one becomes competent. Once competent, successful achievements provide the sense of accomplishment.
