Retirement is a work in progress. I try to figure out my day, and what I know about myself is that I need structure.

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

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.

After I went through two years of not winning an event, what kept me going was winning one more major. Once I won that last U.S. Open, I spent the next six months trying to figure out what was next. Slowly my passion for the sport just vanished. I had nothing left to prove.

Our voting records are not necessarily the same, but, you know, we're all Texans, and at the end of the day, we try to help each other out.

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