Tennis is a mental game. Everyone is fit, everyone hits great forehands and backhands.

In my case, I can sincerely say that nothing is impossible... When I was saying I want to be No. 1 of the world, and I was seven or eight years old, most of the people were laughing at me because it seems like I have one percent of chances to do that, and I've done it.

Building a solid foundation in the early years of a child's life will not only help him or her reach their reach their full potential but will also result in better societies as a whole.

But, it's because we have a harder way to succeed in life as Serbs because of the past that we had and because of the history that we had. We have to dig deeper and we have to do much more in order to be seen and to be spotted.

You have to consistently be successful to be one of the top players in the world, and everything is possible in life.

I had to listen to the classical music because it calms me down, calms my nerves down.

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

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.

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.

And when I was saying I want to become number one of the world and I was 7, 8 years old, most of the people were laughing to me. Because you know, it seemed like I have one percent chances to do that. And I've done it.
