If you're a champion, you have to have it in your heart.

There were times when deep down inside I wanted to win so badly I could actually will it to happen. I think most of my career has been based on desire.

I wanted always to appear strong and in control . . . .Then the cookie began to crumble.

Losing hurts me. I was determined to be the best.

Training the body to obey the mind as I have done differs from the more conventional method of getting the mind to obey the body.

You're always striving to play that perfect match.

To be a tennis champion, you have to be inflexible. You have to be stubborn. You have to be arrogant. You have to be selfish and self-absorbed. Kind of tunnel vision almost.
