Ana Ivanovic

I do miss competition, but I get to travel a little bit on my own terms, which is a little bit different. And I get the chance to walk around, explore, and not have to save my energy for the match days.

Fame and success and titles stay with you, but they wear out eventually. In the end, all that you are left with is your character.

There's really not much friendship between the girls on tour. There's so much rivalry and jealousy, so everyone just hangs out in their own camp. In the locker room and players' lounge, you can feel the jealousy.

Everything in moderation. I keep a healthy body, a healthy look. It's important not to be obsessive about anything - fitness, training, eating - because then you end up focusing on only that. And you can't obsess about anything when you're on the road.

For my fifth birthday, I got a small tennis racket. That's how I started.
