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.

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

Competitive toughness is an acquired skill and not an inherited gift.

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.

I always looked ahead.

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

Ninety percent of my game is mental. It's my concentration that has gotten me this far.
