Some people do have softer boundaries.

The main thing is not a matter of wanting to win; the main thing is being scared to lose.

Tennis taught me so many lessons in life. One of the things it taught me is that every ball that comes to me, I have to make a decision. I have to accept responsibility for the consequences every time I hit a ball.

Bobby Riggs was one of my heroes. I admired him. That's one of the reasons I beat him - because I respected him.

At 62 you want to keep moving; that's important.

I knew after my first lesson what I wanted to do with my life.

I feel that tennis is an art form that is capable of moving the players and the audience - at least a knowledgeable audience-in almost sensual ways. When I'm performing at my absolute best, I think that some of the euphoria I feel must be transmitted to the audience.
