I really try not to read the tennis articles, because a lot of times they're guessing at how a player is feeling, and I like to keep myself kind of open minded about how I'm feeling, rather than have someone else explain to me what's going on.

There is a lot of pressure on tennis players like other sports that are singular like you're not on a team. When all the pressure rides on your shoulders, it can be a lot different. Team sports you share those moments with the teammates. You share the pressures. You share the wins. You share the losses. You have a coach that can change the course of matches. But in tennis you're out there by yourself. There are no caddies. There are no coaches. You do it alone in the arena and I think that ups the ante a little bit.

The good news is I have time.

You can kick a ball into the net, throw a basketball into the net. Tennis is complicated. It'll make a lot of great athletes run the other way because they can't be successful initially.

America has an interesting global role, don't we? It certainly seems to be changing. Our government right now has a softer hand than we've had in the past, but I still think that we're the global behemoth.

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

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.
