I decided to play tennis not because I wanted to be a professional player, but because my parents wanted me to get involved in something so I wouldnt be running around the streets in Serbia.

I love the sport. I love competing. I love battling. I love being out there and, you know, playing in front of crowds. This is what I have been doing since I was a child, so, you know, there's nothing else that I want to do at this point.

I've been a professional for I think 13, 14 years. It's not easy hitting balls every day and staying really motivated throughout the whole period. It's normal [that] you're going to have ups and downs. But I found my way again. And I love the sport. I love competing. I love battling. I love being out there and playing in front of crowds. This is what I've been doing since I was a child. There's nothing else that I want to do.
