I realized that with hard work, the world was your oyster. You could do anything you wanted to do.

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.

My first U.S. Open I think was just very special for me because that was sort of the beginning of what was a 'Cinderella' story for me.

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.

Losing hurts me. I was determined to be the best.

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.

Don’t let a first-set victory lead into a second-set slump
