What I like about the USTA is that it's developing systems to help the coaches coach better.

Even the poor can be fat in the U.S.

I've been lucky enough to primarily work for myself over the years.

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.

There's a reason why Federer and Nadal are so gracious when they lose. They sleep well at night knowing that they've given their best.

You can look directly at the NFL and see how successful they've become because they have central control, central voice, and it doesn't mean that the owners don't have a say, but the commissioner runs it, and he's the one who speaks for them when they go out and do commercial deals.

We lose a lot of young athletes because tennis is such a difficult sport. It's not like kicking a soccer ball.
