Obviously, matches and all that stuff takes its toll on your body and so forth. But as you get sort of a bit older, a bit wiser, and a bit more experienced, you know also how to handle it.

I definitely feel there's room for improvement.

You know, I don't only play for the record books.

My dad said if you become a tennis professional just make sure you get into the top hundred, because you have to make a little bit of money. You make a living so you can pay your coaching and, you know, your travels.

I used to do a lot of video analysis early on, but more for pleasure and looking at my own technique.

The serve, I think, is the most difficult, you know, in terms of coordination, because you got the two arms going, and you got to toss it up at the right time so.

I don't mind fans coming up in a friendly, respectful way. That's all part of the fun of being a top tennis player. But if people take pictures without permission, particularly if my children are in the shot, I feel uncomfortable.
