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.

What I learned as a young child continues to have a tremendous impact on my life today.

Tennis players we're always playing in center courts that feel like arenas. And when we get on the court and the crowd cheers your name or salutes you - it's like you're a gladiator in the arena. And everyone is cheering - and you're fighting, you're screaming, during your strokes - it feels like you're an animal, fighting for your life.

We only have one life and one body to care of, and we better do it right. You never know what tomorrow may bring and so we better live this life the best we can and be grateful for everything we have.

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 know that success does not come at once, it is not a thing achieved overnight. It is the result of many, many, many years of working and trying to achieve goals.

I have always valued the care for my body, and my mind and had holistic approach to life. I always thought this is utmost importance for my tennis.
