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.

I had a unique privilege to have a good start in life and a chance to develop my talents.

It's always easier if you have the support of your family, if you're not alone. I came from a country that has been through a lot of troubles in the last 20 to 30 years, but we have been through them together.

I never wanted to change countries; it's something that is part of me.

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.

In order to stay where I am - and I want to do that - I have to stay dedicated as well as I have been before I became No. 1.

Those born into poverty or on the margins of society require our extra support to realize their dreams.
