Each year represents new challenges and obstacles. You have to adjust.

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 haven't been in tennis for that long, but what I can say is that we have a lot of young guys at the top who are willing to do a lot of good things for tennis in general.

The history of our country is cruel. We have to face those issues or, should I say, we had to. Not anymore I hope, because we are going in the right direction, and we are ready to forgive, ready to move on.

It is very important and my success very much depends on the harmony that I feel in my private life. It is essential for me to be happy in my private life. And if it continues, I am able to continue playing tennis.

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

My strokes just weren't there.
