My mother is a special story. She went through so much to bring us up, four men at home, especially when our country was going through really difficult times.

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.

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.

My father believed in me many times more than I believed in myself.

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.

Tennis is my life, obviously; I need to focus, I need to win. But it's not the only thing. I'm not going to play forever.

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.
