As a tennis player you can win and you can lose, and you have to be ready for both. I practised self-control as a kid. But as you get older they both - winning and losing - get easier.

Everyone is entitled to have their own opinions.

Anyone could become a star, but everyone must be a human being.

Don't think about being the number one in the world, try instead to get through today's program as well as you can. Then we will see whether one day you'll end up as number one or number 100.

If I am not playing at one hundred percent, it is going to be very difficult for me to win.

I do notice that I am tired.

I am going to fight for important things.
