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 would want to bring up my children. Therefore, I have no dream to make my mark. Instead, I enjoy economic freedom my hard work has given me. It means that I can give my children the best start in life.
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 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.
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.
Golf can be tougher than tennis when things go wrong, because you can't explain things by saying that your opponent played better than you. It's a cruel sport in that way.
I don't really spend money like crazy. I buy what I need and what I really want, and if I'm buying expensive things I do think about the purchase many times before I buy it.
My parents paid me small amounts for cleaning my room or cleaning the dishes and stuff, but I never really had a real job before I started on my professional tennis career.
