I always try to adjust to the situation.

Joking around is part of my personality, just who I am.

Tennis players we're always playing in center courts that feel like arenas. And when we get on the court and the crowd cheers your name or salutes you - it's like you're a gladiator in the arena. And everyone is cheering - and you're fighting, you're screaming, during your strokes - it feels like you're an animal, fighting for your life.

My mother is a special story. She went through so much to bring us up, four men at home, especially when our country was going through really difficult times.

I haven't been in tennis for that long, but what I can say is that we have a lot of young guys at the top who are willing to do a lot of good things for tennis in general.

It's interesting that I had such a close relationship with my grandfather. Because your parents always judge you: they say, 'You shouldn't do this, you shouldn't do that.' But with your grandparents you have a feeling that you can say anything or you can do anything, and they will support you. That's why you have this kind of connection.

What I learned as a young child continues to have a tremendous impact on my life today.

As a kid I was creative.

I am very skinny.

It was very unusual for a boy to play tennis in my country.

I've had my ups and downs in my private life.

I embraced, I think, the process of becoming No. 1 of the world, which was long and difficult, but it's sweeter in the end.

I cannot guarantee anything.

I want the same thing I've wanted since I was 7 years old. I want to be No. 1.

You have to consistently be successful to be one of the top players in the world, and everything is possible in life.

My grandfather went through a lot in his life.

I always try to have something that keeps my mind relaxed, keeps my mind a little bit off tennis.

Mostly the problems when I was down were caused by myself. There were times when I was not responsible enough or decisive enough.

I'm happy, my family's happy, everything is going well.

I am fast and very powerful on the court, so this is what matters.
