Hell be lucky to last five or six years on those knees. What it might have to come down to is playing less on hard surfaces and playing more on forgiving surfaces.

The first thing I would do is create one office that controlled all of pro tennis so you had one central voice that spoke for tennis. Central governance is something that's really held the sport back and will continue to do so.

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.

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

If I had to choose one man to play for my life, it would be Nadal.

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

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