I'm trying not to pay too much attention to the rankings because calculations can distract you.

You can not say you're unhappy because you have to travel, have to play this tournament, having to play sports ... You can't because you chose to play it and you love it. I'm tremendously grateful for the support I have received from my family and the close ones.

The confidence is there, the game is there, but physically you can't fight nature sometimes. You can't do much about it.

We spent all day travelling, living away from the people you love, not sleep in our own bed ... We are far from our own houses. We live in hotels, clubs. And now that I am a father it is much more difficult.

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 still feel young as far as motivation is concerned, and also the challenges that I have for the future and what I want to achieve. So I just hope this successful streak is extended to the fullest.

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.
