I don't make a habit of watching tennis matches, but I try to watch all the major finals. I try to make time for that. So unless I have something going with the kids where I can't, I try to watch, and I enjoy that.

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

I have seriously thought about retiring, but that was on a good day. On a bad day I've thought about killing myself.

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.

If you go to school and practice for five days a week, it still gives you two days you can go and see your friends, you can go to the movies, you do whatever you like to do.

I just travel all the time.

Tennis is not like other sports where the coach is hired by an independent entity, and that makes a huge difference in the dynamic.
