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

In tennis you move a lot. Golf you dont. In tennis, you can have a bad half-hour, but you cant in golf. You can lose the first set in tennis and still win.

I enjoy life. I always enjoy jokes.

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.

If you become great, then you can become happy. If you're happy first, it's much more difficult to be great.

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

I just travel all the time.
