I knew I was the second-best tennis player in the state of Florida and No. 8 in the United States of America when I was 12 years old and I couldn't tell you what I was in baseball, but I liked my chances in tennis of getting a scholarship to college.

I think all of us who kind of live within the sport recognize that Davis Cup certainly could be a little more visible if perhaps there were some adjustments made to it, and it was made a little bit more easy to understand for the fans, if there's a little bit more of a start and finish line.

When I turned professional, what I was really aiming for was to be in the top 100, try to hold the top 100 for ten years, and just be in the show, and have a nice career. It's more than I could have ever hoped for. I worked awfully hard for it, but there are other people who worked just as hard and didn't get the breaks. I recognized that I've been lucky and being able to live this life that I wanted since a young age. I really went after it with everything that I have and somehow it worked out.

The dumber you are on court, the better you're going to play.

Flying has opened up new horizons for tennis.

Focusing on one thing can be tough, and people with fewer options are more apt to concentrate on what they're doing. There's probably something to hunger.

I think all of us are shaped by the choices we make.
