I am the greatest tennis player. The other players are like coins in my pocket that I give to a homeless man.

Joking around is part of my personality, just who I am.

I know that success does not come at once, it is not a thing achieved overnight. It is the result of many, many, many years of working and trying to achieve goals.

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

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 want to win and I feel that pressure, but my career will not be a disaster if I do not win there. It is a dream to fulfill.

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.
