I think you have to improve every day a little bit so you don't have one day where there's a big thing coming.

I prefer playing ATP tournaments and Davis Cup competition rather than Olympic Games.

When you win in straight sets, where is the challenge?

Guys like me, we have a different style that makes it hard to break in easily. When I was 18, 19, I felt like I was just a boy, body-wise and mentality-wise. I had to fix everything together.

I need to end up with someone who is strong, intelligent, independent, someone I really admire - sensitive, sensuous, warm, a sense of humor.

I went to a performance-art high school, and a teacher there was signing me up for open-mic nights at the comedy club. I think about it now, and I think, 'Well, that may be inappropriate,' but it was great!'

I love a good Steve Martin, Martin Short scene where they're being super physical - I don't mean to compare myself - but I relate to their type of comedy because they do crazy stuff but come at it in an honest way.

On the whole, a director who make the set a comfortable place to work is really important, whether it's a comedy or drama.
