In the seventies we had to make it acceptable for people to accept girls and women as athletes. We had to make it okay for them to be active. Those were much scarier times for females in sports.

A champion is afraid of losing. Everyone else is afraid of winning.

Martina and I went through a very bad five years. Everything's very good between us now, but it was a long haul.

Don't be afraid to hit the ball.

Winning is very tangible, it's very exciting, it's very pleasing, but it's momentary. If you can do things that last, that each generation can build upon, then that's when you're cooking.

Champions take responsibility. When the ball is coming over the net, you can be sure I want the ball.

No matter how tough, no matter what kind of outside pressure, no matter how many bad breaks along the way, I must keep my sights on the final goal, to win, win, win-and with more love and passion than the world has ever witnessed in any performance.
