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

In tennis, at the end of the day you're a winner or a loser. You know exactly where you stand... I don't need that anymore. I don't need my happiness, my well-being, to be based on winning and losing.

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

The difference is almost all mental. The top players just hate to lose. I think that's the difference. A champion hates to lose even more than she loves to win.

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

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

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.
