Of all my achievements in tennis, I'm probably as proud of my record on clay courts as any of my Wimbledon, U.S. Open or French singles titles.

If you can react the same way to winning and losing, that's a big accomplishment.

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've had a lot of fear in my life, from fear of flying to fear of making a speech in front of a lot of people.

A champion hates to lose even more than she loves to win.

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.

Find something that you're really interested in doing in your life. Pursue it, set goals, and commit yourself to excellence. Do the best you can.
