Chiropractic gives me the flexibility I need to keep in the game.

Some people say I have attitude - maybe I do... but I think you have to. You have to believe in yourself when no one else does - that makes you a winner right there.

I don't focus on what I'm up against. I focus on my goals and I try to ignore the rest.

Just believe in yourself. Even if you don't, pretend that you do and, at some point, you will.

My motto is: I'm alive, so that means I can do anything.

In my mind, I'm always the best. If I walk out on the court (and) I think the next person is better, I've already lost.

Of course, I want to be number one. But being happy and healthy is the most important thing.

Tennis is mostly mental. Of course, you must have a lot of physical skill, but you can't play tennis well and not be a good thinker. You win or lose the match before you even go out there.

It's nice to have a situation where you can make it fun.

I've been giving this lecture to first-year classes for over twenty-five years. You'd think they would begin to understand it by now.

Death is the stone into which our oblivion hardens.

Every company should work hard to obsolete its own product line - before its competitors do.
