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

When I was younger, I was a robot. Wind her up and she plays tennis.

I love hiking in the mountains in Aspen. Breathing the clean, fresh air is great. Plus, it gives me a cardiovascular workout and firms my legs.

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.

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.

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

You're always striving to play that perfect match.
