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.

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.

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.

You're always striving to play that perfect match.

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

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.

The great high of winning Wimbledon lasts for about a week. You go down in the record book, but you don't have anything tangible to hold on to. But having a baby -- there isn't any comparison.
