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

I am there to play tennis and represent the U.S., but I'm also aware that not everyone's going to be able to think that way.

It does take a great hunger to be successful at anything.

There are certainly great cities in America that don't have ATP and WTA events. Our fans are very provincial. They want American champions.

If you don't want to practice, unless you have a hard-nosed coach, you don't have to.

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

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.
