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.

After being at the top, I don't think I could play senior tournaments, because you know how good you were. I don't know if I would enjoy that, being half of what I was.

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 I win several tournaments in a row, I get so confident I'm in a cloud. A loss gets me eager again.

Whatever your goal in life, be proud of every day that you are able to work in that direction.

I realized that with hard work, the world was your oyster. You could do anything you wanted to do.

You're always striving to play that perfect match.
