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.

I had to know at least two languages.

My success has a lot to do with my private life. I've matured a lot by first becoming a husband and now a father. My life is in the right direction. And that helps a player to thrive. One thing is linked with the other. My private life has helped me.

I think luck falls on not just the brave but also the ones who believe they belong there.

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.

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

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.
