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

If I win several tournaments in a row, I get so confident I'm in a cloud. A loss gets me eager again.

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 can definitely say the same thing [discussing Steffi Graf's claim that she had played against at least one top player who used steroids]. Steroids can really make a difference, physically and mentally. I'd be really disappointed if I had been ranked No. 2 behind someone who took steroids.

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.

Being famous before you've formed your personality, before you have that self-esteem, is dangerous.

Training the body to obey the mind as I have done differs from the more conventional method of getting the mind to obey the body.
