I don't do heavy weights at all.

Tennis has never been the most important thing in my life. My family, my health, my happiness...they are more important to me. On court, I want to win. Off court, I want to be a better person. Tennis is a path to my future.

I don't spend a lot of my time in the locker room. That's my least favourite place in the world.

My shoulder's not where I want it to be, but I'm doing a good job of monitoring it.

Tennis has given me this wonderful life and I'm very grateful for it.

When I make commitments I like to stick to them, especially when I'm giving back to kids. Just giving them an example of what they can achieve. I love giving back to kids. It's fantastic.

I was very disappointed (at the U.S. Open), and I went out there and I worked really hard.
