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.

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 embraced, I think, the process of becoming No. 1 of the world, which was long and difficult, but it's sweeter in the end.

My father had never watched tennis, never liked tennis too much. He said, 'OK, we buy a racket, we watch together,' because we didn't know anything. It was a process of learning together that made it more interesting.

It is my goal to win every time I play. But on the other hand, I also seek a balance of compassion and respect for the other players. I understand that everyone goes through difficult times, either mentally or physically, to cope with their life, to live the sport.

I always try to adjust to the situation.

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