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.

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

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

I think to be 'tough' means you look relaxed. So you have to be tough to win tournaments. But you don't want to be so tough on yourself.

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.

We always learn more from the losing than the winning.

As it becomes longer at No. 1, I feel more and more pressure. Everybody is trying to grab every piece of me.
