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.
The confidence is there, the game is there, but physically you can't fight nature sometimes. You can't do much about it.
I've had my ups and downs in my private life.
I'm a happy man, because I am successful in what I do, of course; but what makes me most happy is I have people around me that I love and who love me back. This, for me, is the most important thing. Nobody likes to be alone.
My father never talked about the sacrifices that the family made for me.
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 always try to adjust to the situation.
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.
We have a harder way to succeed in life as Serbs because of the past that we had and because of the history we had.
I had to know at least two languages.
I feel the pressure.
I never wanted to change countries; it's something that is part of me.
Imagine a part of the U.S.A., from which the U.S.A. started - where is the cradle of your history? This is Kosovo for Serbia.
I love football and it's the sport I would really like to play. I've said on national television here that I would really love to play for one of our football clubs when I finished my tennis career.
Nobody actually played tennis in my family.
I'm happy, my family's happy, everything is going well.
I don't think there has been enough communication between the players and the tournaments. In one sense it's just as much the players' fault. Players talk between each other and in the locker room about things that can be improved and then when the time comes to talk and really do something about it they stop.
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.
As a kid I was creative.
I always try to have something that keeps my mind relaxed, keeps my mind a little bit off tennis.
