Tennis has given me so many opportunities, and I feel very lucky to have achieved whatever I have, especially coming from a country that does not have a great history in the game.

Coaches were all saying that I was really talented and I had potential, but coming from Serbia, it wasn't easy. The '90s were the hardest years for our country - we went through two wars.

Everyone wants to be happy - people find happiness in different ways. While you want to pursue your career 100 percent, I think it is very hard to give 100 percent in something else. It's important to find this balance, and priorities change throughout life.

I think it's better not to mix professional life and personal life - although it is hard.

I had a really bad temper, when I was growing up. Sport helped me channel that temper into more positive acts.

I think they need to get a more reliable way of watching television on the laptop. Because I travel so much, if I want to watch my favorite sports team it might not be showing in that place, so I want a reliable way to watch whatever I want to watch on my laptop.

Nobody I ever broke bread with, and I see players all the time, talked about using their head running the football.

There are certain things that I always dreamed of, like fighting in the UFC. There's just certain things that I feel like haven't been accomplished there. There's such great women coming up in the sport; seems like a wonderful time to be in women's MMA.
