If you're creating something that has some sort of cultural currency - if the idea is getting out there - then that will probably yield money in some form, whether it's through selling art or selling books or being asked to give a lecture.

The way I make art, the way a lot of people make art, is as an extension of language and communication, where references are incredibly important.

Creating is about sharing ideas, sharing aesthetics, sharing what you believe in with other people.

Art is not always meant to be decorative or soothing, in fact, it can create uncomfortable conversations and stimulate uncomfortable emotions.

A lot of people thought I got famous as a studio artist, then decided to cash in on it. But it actually was just a matter of survival for many years, and I felt it was really important for me to be able to say whatever I wanted with my street art and fine art.

I think "punk" should really be defined as paving your own way creatively and by defying any sort of orthodoxy or commercial pressure.

I've met Obama a few times, and I think Obama's a quality human being, but I think that he finds himself in a position where your actions are largely dictated by things out of your control. I'm not giving him a pass for not being more courageous, but I do think the entire system needs an overhaul and taking money out of politics would be a really good first step.
