I have a great family, great kids. I have practically everything, you know? Sometimes I have to pinch myself. It's really true: Life starts at 50.

The ball is round, the game is long.

If you're a good experienced player, you wknow what it takes to do. If you're in trouble, you know how to change. One hundred percent of my game is instinct. I never stop and think I'm going to hit a ball crosscourt or down the line. I just do it.

It's not easy to part with the trophies. However, I do need to have some long-term financial security for those close to me.

When I retired from tennis I wanted to do other things with my life.

I play tennis five hours a week, from Monday to Friday, for one hour every day. I like to be fit. If I can't exercise, I feel bad - I need to sweat and run to feel like I'm in good shape.
