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.

When my boy arrived in this life, on this planet, it was completely a new dimension of experience for me and my wife. I'm still riding on the wave of that experience.

Mostly the problems when I was down were caused by myself. There were times when I was not responsible enough or decisive enough.

I'm very fortunate to have the support of the people around me, I feel happy because my wife helps me and people who are close.

Nadal's the best player in history on [clay], and he is one of the best-ever players that played this game.

I don't like to compare years, honestly. I think every year is a different experience, a different challenge. You grow. You evolve as a person and as a player.

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