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.

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

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.

It was different when I was young, aged 20, playing the French Open. I didn't have so much experience. I just played tennis because I loved the game.

Ever since I was a kid, I've always thought it very important to be happy inside. There's a lot of bad things happening in the world, but it's important to try to stay happy and appreciate what you've got, and don't look externally for the happiness.

It's very important to take care of yourself. Everyone's lives are so busy. Take at least an hour a day to recharge and do whatever makes you better. For grown-ups, whether it's a spa, sitting in a park with a book, or coffee, take time for yourself.

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.

When I was starting out, it was almost impossible for me to get visas to travel to tournaments.

I was watching tennis on TV, and between games, they were showing a commercial for a tennis school. I wrote down the number, gave it to my mom, and said, 'This is what I want to do.' She thought it was a joke, but I was very stubborn, and I kept bringing it up.

I like men who have goals, something that they are passionate about and work hard to achieve. A good sense of humor is important too. And I like tall guys!
