You're always striving to play that perfect match.

There were times when deep down inside I wanted to win so badly I could actually will it to happen. I think most of my career has been based on desire.

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

If you can react the same way to winning and losing, that's a big accomplishment.

I was labeled at a young age - Miss Unemotional, Miss Cool, and that would carry over to my press conferences.

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.

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.
