Roger Federer

You always want to win. That is why you play tennis, because you love the sport and try to be the best you can at it.

I'm a very positive thinker, and I think that is what helps me the most in difficult moments.

To handle that stardom, the red carpets, the photo shoots, people all of a sudden recognizing you and following you in everyday life, it's a bit weird. It's strange, and it can have funny effects on you in terms of do you like it or don't you like it. Some people run away from it, some people embrace it; I found a good middle ground.

Before, I guess, mum and dad were everything, but now, in my case, I had two new girls and all of a sudden they're completely dependent on you and there's a third generation. It's a funny shift all of a sudden. You have the babies, you have yourself and then you have your parents.
