I've got to wear sunglasses everywhere, all the time, even if its indoors or at night time, to be recognized. That's part of my job. I cannot take off my sunglasses. For me, staying in the United States was so dark because I can't take them off.

Before 'Gangnam Style' I was not a good attitude artist.

I'm not that good looking. That's why 'Gangnam Style' works. If someone handsome uses that phrase it's just awkward. But if someone like me uses it, it's funny.

As an artist, the more experience, the better the creation. I'm a very positive person.

If a Korean artist reaches to the top, we're all ready to stand up and applaud for him or her.

I need to show the world that my final goal is to perform huge concerts like Madonna.

If I say, 'Hey, I'm Psy.' 'Psy?' 'The guy from the video on YouTube?' 'Oh.' I hate that. I've got to be more popular than the video. So I need to keep promoting myself.
