You don't need planning permission to build castles in the sky

The grumpier you are, the more assholes you meet.

I used to tell everyone I met to be an artist..... I don't do that any more.

I know street art can feel increasingly like the marketing wing of an art career, so I wanted to make some art without the price tag attached. There's no gallery show or book or film. It's pointless. Which hopefully means something.

People seem to think if they dress like a revolutionary they don`t actually have to behave like one.

It's impossible to predict which paintings will last and which won't. In New Orleans I painted on a dilapidated shop in a street littered with abandoned cars and rotting mattresses, then two hours later the piece was gone. It turned out I'd picked the side of a crack house and the proprietor didn't like the attention.

Should #‎ graffiti be judged on the same level as modern art? Of course not: It's way more important than that
