If you can react the same way to winning and losing, that's a big accomplishment. That quality is important because it stays with you the rest of your life, and there's going to be a life after tennis that's a lot longer than your tennis life.

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.

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.

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

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

Competitive toughness is an acquired skill and not an inherited gift.

Ninety percent of my game is mental. It's my concentration that has gotten me this far.
