Don't make things too complicated. Try to relax, enjoy every moment, get used to everything.

You will always have ups and downs in your life and your career, but just stay positive and go for it.

When I was a kid, I was always dreaming to one day be the No. 1 player in the world, to win Grand Slams.

Of course it's tough to reach the number one place and also winning grand slams.

Winning the second grand slam, it was a bit different. I don't have anything to prove anymore. I am at the top: number one.

My whole life, I've been working really hard, and I can say I'm a grand slam champion.
