What's the Hardest Thing?

The inner game of tennis is not a tennis book. It's something else, which is why it's now sold something like two million copies.

I get asked to give a lecture about the inner game to the infia mon y, play no classical instruments. At the end, they applaud politely, except for the conductor who comes up and says, i'm not going to believe this till i see it.
