“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.”

I tell myself I use art to promote dissent, but maybe I am just using dissent to promote my art. I plead not guilty to selling out. But I plead it from a bigger house than I used to live in.

You can win the rat race but you’re still a rat.

I don’t believe in anything. I’m just here for the violence.

I wanted to highlight the destruction in Gaza by posting photos on my website – but on the internet, people only look at pictures of kittens.

If it doesn’t matter, get rid of it. If you can’t get rid of it, it matters.

A lot of people never use their initiative because no-one told them to.

Graffiti is one of the few tools you have if you have almost nothing. And even if you don’t come up with a picture to cure world poverty you can make someone smile while they’re having a piss.

The thing I hate the most about advertising is that it attracts all the bright, creative and ambitious young people, leaving us mainly with the slow and self-obsessed to become our artists.. 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.

Bus stops are far more interesting and useful places to have art than in museums.

All artists are willing to suffer for their work. But why are so few prepared to learn to draw?

Nobody knows what you feel inside unless you tell them.

If you want to say something and have people listen then you have to wear a mask. If you want to be honest then you have to live a lie.

Gaza is often described as ‘the world’s largest open air prison’ because no-one is allowed to enter or leave. But that seems a bit unfair to prisons – they don’t have their electricity and drinking water cut off randomly almost every day.

A lot of mothers will do anything for their children, except let them be themselves.

T.V. has made going to the theatre seem pointless, photography has pretty much killed painting but graffiti has remained gloriously unspoilt by progress.

Although you might have to creep about at night and lie to your mum it’s actually one of the more honest art forms available. There is no elitism or hype, it exhibits on the best walls a town has to offer and nobody is put off by the price of admission.
