You can't give up! If you give up, you're like everybody else.

Single-mindedness. I hate to say it because I don't think it's the best thing for developing a person, but the single-mindedness - just concentrating in the one area - that's what it takes to be a champion.

I was very, very shy as a younger girl, just petrified of people. Tennis helped give me an identity and made me feel like somebody.

If you're a champion, you have to have it in your heart. You can have the greatest coaches in the world, all the opportunities to play, and the greatest equipment, but if you don't have it inside, you're not going to make it. On the other hand, if you don't have any of those luxuries but you have heart and courage and the guts to go out there and grind it out, then you'll make it.

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

I'm not getting within 20 feet of a married man ever again - not even talking to one!

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