When I play, I'm boiling inside. I just try not to show it because it's a lack of composure, and if you give in to your emotions after one loss, you're liable to have three or four in a row.

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

I still have this image: I can't be controversial, I can't say things.

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.

Not every child is cut out for an individual sport.

If you're a champion, you have to have it in your heart.

Once you've been number one, you can never be satisfied with less.
