You learn something when you don't play well, and I figure that helping people, it makes me very, very happy.

I want to play for my country, play for everybody, and I want to be there. I just feel like I have so many feelings and I want to play in the Olympics and feel how special if I can win that tournament.

When I was 13 my dream was to play the U.S. Open. Now it's to win it.

Although I have won many times now, each time when I have a lead, I start to think about winning. It's very difficult not to think about winning. Every time, there are new challenges. Every time, there are new issues to overcome.

I always believe that every one of us is working hard not only for our own performance but also to give something significant back to the societies we live in.

You learn from your mistakes, and I think it's a good thing as long as you learn something.

In golf, it's almost impossible to be perfect on each shot; that's the fun and challenge of golf.
