The Inner Game of Tennis, by Timothy Gallwey
Yes... yes! I'll gladly recommend this over any book of philosophy. (Different philosophers click with different people.) Granted, I was thirteen and a tennis player when I first read it, but I haven't played tennis seriously in over twenty years, and I still use the lessons in this book any time I practice anything physical. Dancing, chopping onions, running, lifting weights, you name it. I use it anytime I need to do something where the real intelligence at work is not part of my conscious mind, including controlling my emotions, but it works best with physical skills.
Gallwey wrote some other "Inner Game" books, but he was a Division I college tennis player, and this was his first book. This is the book he wrote about the sport he knew, without knowing it would be a best-seller. I don't know if the others were written to the same level of quality.
