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

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.

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'm not suggesting that the entire nation can't be successful, but there's something to it when you have 150 cable channels and the Internet at your fingertips and video games and all kinds of ADD-addled devices like my iPhone and your BlackBerry and things that keep us busy.

The good news is I have time.

Us going out there and performing our best. That's how I define success. I'm not going to define it for us by the wins and the losses as much as by the effort and how we handle ourselves.

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.
