Write it down. Put it someplace you will see often that day. It can be a quote about the game itself, about leadership, or more general about life. Match it to your stage of the season. For those of you who know my far side, you will understand then my two rules in this key area of pushing yourself on the court.
Winners never fear risking to lose.
Go watch levels of play higher than you compete in - the 18 and unders if a Junior Olympian, or collegiate matches, and the National Team any time you can catch them on TV or in person. Watch one player who you want to be like as they do the whole rally, by not focusing on the ball, but their actions before, during and after the rally, before during and after each contact. There is much more learned by what is done before the ball is touched, that you need to develop too. I will be passing these along to others, starting with the Paralympic and Olympic staffs, as part of the team around the team we have here. If you have an idea that you think might help you or the team programming be better, share it, for unlike items, when you share ideas, you still have yours, while adding new ones to our tools to be our best.
