playing your own game

In relation to my previous post on 'being good', I came across this quote in a discussion about competing. It's Rod Laver, the Australian tennis champion:

You do the best you can. If you don't play your own game, you're going to lose it anyway. If you start to worry about the importance of the win before it happens, you're going to have yourself in a complete panic. You play the shots as you see them. That, and don't start wishing the shots to go in. When you start wishing, you are in trouble.

You play the shots as you see them. Nice.
