Without a doubt, there's huge satisfaction when a relatively smaller nation can take on a bigger nation and defeat them. There's a lot of pride in that.

I think there's no reason the Davis Cup couldn't be as powerful and popular and profitable as any of the four majors are today, given some changes.

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

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.

One of Nadal’s strengths is that he’s so humble, that he’s surprised at what he has achieved, and that he has never bought into his greatness.

I think all of us are shaped by the choices we make.

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.
