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.

I got married, going to become father soon, being No. 1 in the sport that I love with all my heart. I mean, it's pretty awesome.

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.

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.

I always try to show my human side to my colleagues and to the whole circuit. More than anything because we are all on the same train, it is part of our work.

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 think if you do not enjoy your time, your life, if you do not live intensely and do not spend time with your family, in one way or another it will be reflected in your career.
