In Korea, it's a tradition to inherit your father's business. Unfortunately, I'm the only son in the entire family, so they were forcing too much.

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.

All the people in Korea are cheering me like I'm a gold medalist or something, so I have a responsibility to my country.

The fact that I'm shouting that I have Gangnam style makes people crack up. Imagine if Brad Pitt was singing the song - would it be funny? A twist is important when it comes to writing lyrics.

I really like the P!nk song with the guy from fun., 'Just Give Me a Reason.'

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.
