For so long people have just taken what I do for granted. It is not easy to do year-in, year-out, to win Grand Slams and be No. 1.

You know, you walk into this place, it's not like walking into Cincinnati or Montreal. This is a Grand Slam. You know, this is what you play for. This is what tennis is all about. Yeah, not many people will remember what happened in Montreal or Cincinnati if you go out and win this tournament.

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.

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.
