I didn't change the world.
I hate competition.
I think it's difficult to be No. 1. 'There's too much attention, too much expectation from other people.
I've had good times and bad times. That's me. That's how I am.
I just want to make everyone happy.
But when I'm losing a few matches, suddenly 'It's his fault', 'He doesn't want to practice', 'He doesn't need it', 'He doesn't care'. And when everything goes well, there are people coming behind the stone, saying, 'Oh, my God, he's back finally, and I was there to help him out'.
I pass through the difficult moments in life, really difficult times on grass, during my seven years of my career. All of a sudden I felt comfortable.
There is no such thing as a perfect player; it doesn't exist.
I can improve it a little bit. But it's my head, it's the way I am. So at the end of the day, I will be who I am and I will win how much I can win.
I definitely want to get out of tennis and try something completely different.
You have to wake up and you have to run if you want to survive.
