Caroline Wozniacki

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

I have a very close relationship with my parents.

I have nothing to lose and think that it's a positive thing that I am young and playing on a good level.

My mom was always the support. I can always go out to her and she'll always find the positive in things.

My dad has always been my coach. And I've spent so much time with him. So he's one of my best friends. And I can talk to him about everything.

One day my dad would say, 'OK, if you want to play tennis I can help you out.' And that's how it started. And I had a goal. I wanted to beat my mom first. And my parents and my brother. And that was the ultimate goal.

I'd like to do a lot of things - whether in design or architecture or business.
