I lost to a better player who played some courageous tennis and deserved to win.

I had to know at least two languages.

Serbian history tells that family is the most important thing and you have to stick with the family.

I'm a happy man, because I am successful in what I do, of course; but what makes me most happy is I have people around me that I love and who love me back. This, for me, is the most important thing. Nobody likes to be alone.

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.

Mangling my racket and an odd swearword on the court is not something I am proud of and it shouldn't happen, but even my coaches have told me that it's sometimes better to let it all out, the anger inside you, because keeping it bottled would just eat you up in the long term.

Nobody actually played tennis in my family.
