Ninety percent of my game is mental. It's my concentration that has gotten me this far. I won't even call a friend on the day of a match. I'm scared of disrupting my concentration. I don't allow any competition with tennis.

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.

My first U.S. Open I think was just very special for me because that was sort of the beginning of what was a 'Cinderella' story for me.

Being famous before you've formed your personality, before you have that self-esteem, is dangerous.

I think team sports probably teach you more about giving - about being unselfish and being flexible.

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.

I always looked ahead.
