Andy Roddick

I got to play in a crowd, play in Wimbledon finals, be the guy on a Davis Cup team for a while. Those are opportunities not a lot of people get. As much as I was disappointed and frustrated at times, I'm not sure that I ever felt sorry for myself or begrudged anybody any of their success.

My worst days are still pretty good days. That's something I might lose in the moment sometimes, but I have a pretty good grasp of it.

I don't think about tennis 24/7. I enjoy time on the lake at my Florida home and just being lazy on the sofa.

I think I have a lot of room for improvement. My serve is okay, but I need to work on a lot of things: return, transition game, backhand.

There have been great champions in every generation.
