I'm not an overly ambitious person; I don't feel like I have to excel.

You're always striving to play that perfect match.

You've got to take the initiative and play your game. In a decisive set, confidence is the difference.

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.

To be a tennis champion, you have to be inflexible. You have to be stubborn. You have to be arrogant. You have to be selfish and self-absorbed. Kind of tunnel vision almost.

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