I'm trying to enjoy my lie as much as I can and I know that tennis hopefully is going to be my life the next 10, 15 years.

My grandfather went through a lot in his life.

I never wanted to change countries; it's something that is part of me.

We spent all day travelling, living away from the people you love, not sleep in our own bed ... We are far from our own houses. We live in hotels, clubs. And now that I am a father it is much more difficult.

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.

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.

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.
