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 want to help children in Serbia and around the world so they can realize their dreams.

Building a solid foundation in the early years of a child's life will not only help him or her reach their full potential but will also result in better societies as a whole.

I don't think, that you can always - you can ever - get your game to perfection, you know. Only if you're Federer.

It's always easier if you have the support of your family, if you're not alone. I came from a country that has been through a lot of troubles in the last 20 to 30 years, but we have been through them together.

This time last year I would have said Federer would beat Sampras's record. Now I'm not so sure. His aura has gone. He's not as dominant as he was, and since I beat him in Australia he's looked frustrated. Players are beginning to challenge him now, especially myself and Rafa. He's got 12 Grand Slams to his name and maybe he will beat Sampras, but now I'm here it will be tough for him.

I had a nice childhood. War and all the experiences affected me as a person and helped me to grow, to change.
