Golfers are forever working on mechanics. My tennis swing hasn't changed in 10 years.

People know me. I'm not going to produce any cartwheels out there. I'm not going to belong on Comedy Central. I'll always be a tennis player, not a celebrity.

If Davis Cup was a little bit less or once every two years, I would be more inclined to play. But the way it is now, it is too much tennis for me.

I let my racket do the talking. That's what I am all about, really. I just go out and win tennis matches.

In tennis, you can make a couple of mistakes and still win. Not in golf. I played three rounds in that Tahoe event, and I was drained. Mentally, not physically.

It's not easy to retire at 31. In one respect I was glad I was done. But after a few years of having fun, I got a little restless. When you're 33, 34, and you don't have a focus, you can get kind of lost. As a man, you feel a little bit unfulfilled.
