It doesn't take much to be a successful artist-all you need to do is dedicate your entire life to it.

There's obviously nothing wrong with selling your art - only an idiot with a trust fund would tell you otherwise. But it's confusing to know how far you should take it.

People who enjoy waving flags don't deserve to have one.

I wouldnt want to be remembered as the guy who contaminated a perfectly legitimate form of protest art with money and celebrities.

Keep your coins, I want change.

But there's no way round it-commercial success is a mark of failure for a graffiti artist. We're not supposed to be embraced in that way. When you look at how society rewards so many of the wrong people, it's hard not to view financial reimbursement as a badge of self-serving mediocrity.

Graffiti ultimately wins out over proper art because it becomes part of your city, it' s a tool; "I'll meet you in that pub, you know, the one opposite that wall with a picture of a monkey holding a chainsaw". I mean, how much more useful can a painting be than that?
