I am not playing Wimbledon because I am allergic to grass.

I was between 2 and 3 in the world for two, three years. That's not exactly where I wanted to be.

Too many people asking too many questions in tennis. Golf is better.

People may say I developed an iron will, but what really happened is that I made myself much fitter. I think an iron will is always supported by fitness.

I just travel all the time. And I was just looking at the schedules now and starting the first week of October I will be every weekend with somebody at tournaments through Christmas. So it gets very difficult to just go away and not do that.

It's flattering to be compared in any way to Tiger Woods, because he's the best player in the world.

I'm certainly not sorry that there were some things I missed. You may think you're missing something at that time but later when you look at it, you didn't miss anything.
