If you go to a big city anywhere in the world and you need a doctor, just ask me. I can tell you who's good and who's bad. I've even considered writing a guidebook.

I never look back, I look forward.

I have always been guided by striving to show the best that I could. That is what kept me going in tennis and it is the same now.

I knew that maybe I couldn't be playing again, but I just wanted to get in physical shape.

I don't ever look back. I look forward.

I don't wake up every day and think about which tournaments I won and which titles I hold. It's something I don't care about.

Tennis has always been a big challenge to me and to be able to play that kind of tennis - well, only tennis can produce these feelings for me.
