I try to be myself and, of course, be a good role model. I don't really find it hard, but you think about what you do and that other people look up to you.

I think that's my personality, to have a good laugh and not to take myself too seriously. And of course I have my things on the court but when I'm off the court I just like to have fun.

I think I'm a really tough player.

It's very expensive to be a professional tennis player with all the travel and the flights and the hotels and everything.

There are so many tough opponents out there and tough competitors so I've never liked to look ahead.

There are a lot of things to my game I can still improve, but everyone can.

I don't know, I always get the question 'how do you feel after the game today?' and, of course, if you're winning you feel great and if you lose you don't feel good. I think that's a pretty obvious question.
