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

People look up to me as somebody who is able to switch the image of our country from negative to positive.

Coaches are very important to players. They're people that are mentors, people that are advising them, people that should be their friends and somebody you can rely on on the tour.

Nadal's the best player in history on [clay], and he is one of the best-ever players that played this game.

As a kid I was creative.

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.

Tennis is my life, obviously; I need to focus, I need to win. But it's not the only thing. I'm not going to play forever.
