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.

I like my groundstrokes, I can say. I like it. That's my game - I'm a groundstroke player and I play pretty aggressive.

I always tried to win. I was as competitive as I am today.

Mangling my racket and an odd swearword on the court is not something I am proud of and it shouldn't happen, but even my coaches have told me that it's sometimes better to let it all out, the anger inside you, because keeping it bottled would just eat you up in the long term.

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 embraced, I think, the process of becoming No. 1 of the world, which was long and difficult, but it's sweeter in the end.

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