Well, I do feel that I carry the responsibility of representing my country wherever I am, and this responsibility came with the success that I had in last couple of years, not just myself but the whole group of tennis players that comes from Serbia. And athletes in general are, in this moment, the biggest ambassadors that our country has.

Even though now I'm pretty popular in my country and tennis is the No. 1 sport, and I'm very flattered that the people recognise me and come up and give me compliments, I'm more a person who likes to have privacy and peace.

When my boy arrived in this life, on this planet, it was completely a new dimension of experience for me and my wife. I'm still riding on the wave of that experience.

I love being around people who care about me, and I care about them.

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 remember as a kid, I was improvising and making little trophies out of different materials and going in front of the mirror, lifting the trophies and saying 'Nole was the champion!'

In my case, I can sincerely say nothing is impossible.
