Tennis is a mental game. Everyone is fit, everyone hits great forehands and backhands.

Those born into poverty or on the margins of society require our extra support to realize their dreams.

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

In my case, I can sincerely say nothing is impossible.

My grandfather went through a lot in his life.

Even though now I'm pretty popular in my country and tennis is the No. 1 sport, and I'm very flattered that the people recognise me and come up and give me compliments, I'm more a person who likes to have privacy and peace.

This time last year I would have said Federer would beat Sampras's record. Now I'm not so sure. His aura has gone. He's not as dominant as he was, and since I beat him in Australia he's looked frustrated. Players are beginning to challenge him now, especially myself and Rafa. He's got 12 Grand Slams to his name and maybe he will beat Sampras, but now I'm here it will be tough for him.
