Yes, I know this is about tennis, and yet I've put it on my music and singing shelf. The first time I read this I'd never played tennis outside of learning the rules and bashing the ball around during gym class. The second time I read it, I substituted the word singing every time Gallwey wrote "tennis" and it worked. It's an excellent book for helping anyone involved in a physical activity requiring great skill AND finesse find their peak performance.
