Daniel, my big brother, is eight years older. I'm lucky he didn't mind hanging out with his little sister and my younger brother.
I started mountain-bike riding two years ago, which is much better than riding a stationary bike in the gym. Mountain biking is a total body workout.
I watch the ball fiercely to see its height and speed off my opponent's racket so I can decide how I want to hit it.
I always have applesauce in my fridge, and when traveling I take protein bars just in case I get hungry. They're my go-to snack.
My mind started wandering. I started playing carefully, instead of playing the way that had gotten me to that point. I had to force myself to keep driving the ball.
It's not so bad that I can't touch my toes. But I'm not one of the most flexible guys. When you look at Novak Djokovic, you'd probably think he's made of rubber.
Anna Kournikova will always be better paid than Lindsay Davenport. The first left the circuit without having won a single title while the second was world number one.
Reaching the top 100 was always my goal since I started to play as a pro. In '05 I came quite close, reaching a ranking of No. 129, but then was stopped by a major shoulder injury.
In tennis, because of the way it's scored, I don't think that scoring one point out of luck is ever decisive in winning. But, of course, it depends on the moment.
I think when you compete every week, when you play under pressure daily, you find your rituals to be 100 percent focused on what you're doing.
I am a guy who likes to do what I am doing with passion, whether it's a soccer match with friends or golf.
Tennis is pretty unforgiving if you are carrying weight. You are expected to wear short skirts, and you are compared to all these 16 and 17-year-olds.
I would like to thank all my tennis fans who were there from Day One when I was No. 1, through my stabbing, and my comeback.
What I put in the stock market, I don't have to touch in my lifetime. I want to live off my bonds. I want to be that safe.
I like my groundstrokes, I can say. I like it. That's my game - I'm a groundstroke player and I play pretty aggressive.
In order to stay where I am - and I want to do that - I have to stay dedicated as well as I have been before I became No. 1.
I have been through two wars in my 24 years, and I know what it's like to be without anything, to see the bombs flying above your head.
I hope that more children have the same opportunities as me, with the same parents as me, that let me be an individual, who gave me freedom, and taught me to believe in myself before anyone else would believe in me.
I love to promote our sport. I love grass-roots tennis. I love coaching. I love all parts of the sport. I love the business side.
It's not so much that I don't like traveling, it's just that I love being home. I love being able to spend time with my friends.
Well, I think, you know, the university and the high schools are also important, but depends how I'm going to do in tennis - well, I hope. I mean, it depends, so I don't know yet.
