I learned that the only way you are going to get anywhere in life is to work hard at it. Whether you're a musician a writer an athlete or a businessman there is no getting around it. If you do you'll win - if you don't you won't.

That's the hard part about sport: as men we haven't started to be in our prime but as athletes we are old people. I needed support. I lost trust and did stupid things.

A good athlete always mentally replays a competition over and over even in victory to see what might be done to improve the performance the next time.

I just want to continue the success and be an athlete that is shown in a good light in New York City.

There is no correlation between a childhood success and a professional athlete.

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.

So much of a professional athlete's success depends upon not necessarily the play itself but how he deals with... always saying how you deal with good is just as important as how you deal with bad.

I'm probably the least flexible athlete you'll find. When it comes to yoga I can't get in the positions and I can't hold them. You have to be pretty flexible to do it. Once you get certain positions you have to have the core strength to hold those positions. It's a pretty good workout.

Meeting sports athletes that are the best in the world is a thrill to this day.

I long for the days when athletes were revered. I want to see the romance return to sports to see people enjoy the game purely for the game and the players.
