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.

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

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

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.

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.

I've had a lot of fear in my life, from fear of flying to fear of making a speech in front of a lot of people.

Relationships are give-and-take, and when you're a tennis player, you're certainly not giving. You have to be self-absorbed. It has to be about you.
