You have to consistently be successful to be one of the top players in the world, and everything is possible in life.

I've had my ups and downs in my private life.

Coaches are very important to players. They're people that are mentors, people that are advising them, people that should be their friends and somebody you can rely on on the tour.

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.

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

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.

I'm happy, my family's happy, everything is going well.
