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

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.

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.

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 think the future also will not belong to those who are cynical or those who stand on the sidelines.

I don't know if I believe in luck. I think I'm very fortunate.
