I originally set out to try and save the world, but now I'm not sure I like it enough.

Modern art is a disaster area. Never in the field of human history has so much been used by so many to say so little.

Speak softly, but carry a big can of paint.

You live in the city and all the time there are signs telling you what to do and billboards trying to sell you something.

I’ve learnt from experience that a painting isn’t finished when you put down your brush – that’s when it starts. The public reaction is what supplies meaning and value. Art comes alive in the arguments you have about it.

You're advised not to drink the replica Arab spring water.

I don't know if street art ever really works indoors. If you domesticate an animal, it goes from being wild and free to sterile, fat and sleepy. So maybe the art should stay outside.
