I'm as patient a father as I am on the tennis court. It takes a lot for me to get really upset, but sometimes kids can get you really cross if they really keep bugging you.

My family is the thing I miss most on the tour.

I did all the right things in so many tournaments. But like I said, sometimes in sports it just goes the other way. Maybe you've already won so much that it evens it out a bit sometimes. I don't know.

The crowds are very important for tennis. It makes you play better, but it can also make you nervous and that's the beauty of it.

Confidence? Are you kidding me? I mean, please. Look, some players grow up and play like that. I remember losing junior matches. Just being down 5-2 in the third, and they all just start slapping shots.

When you do something best in life, you don't really want to give that up - and for me it's tennis.

My game is a lot about footwork. If I move well, I play well.
