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

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.

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

Now that I'm losing some, I can see how tough I was -- the killer instinct, the single-mindedness, playing like a machine. Boy, that's what made me a champion.

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.

I think team sports probably teach you more about giving - about being unselfish and being flexible.

Losses are always a relief. They take a burden off me, make me feel more normal. If I win several tournaments in a row I get so confident I'm in a cloud. If I lose I go back to the dressing room and I'm no better nor worse than anyone else. A loss gets me eager again.
