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.

There used to be a lot more politics in the Olympics, when the Soviet Bloc committed a lot of resources for propaganda purposes.

Tennis is more than just shots. It's about being clutch and beating the people on the other side of the net.

You need to make sure everyone is healthy first and foremost.

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.

Getting to number one in the world without a coach is highly unlikely.
