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.

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.

Mostly the problems when I was down were caused by myself. There were times when I was not responsible enough or decisive enough.

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 still feel young as far as motivation is concerned, and also the challenges that I have for the future and what I want to achieve. So I just hope this successful streak is extended to the fullest.

I try to enjoy what I do, and every moment of the life that I have is a blessing. What else can you do but to be happy and try to bring that joy to the other people around - especially in the tournaments. Everybody has bad days. I'm not always funny or laughing.

The confidence is there, the game is there, but physically you can't fight nature sometimes. You can't do much about it.
