“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 one thing you can rely on is if you get disturbed halfway through a painting and it looks a bit naff, then someone will preserve that piece, remove it and a few months later it’ll be paraded round Sotheby’s by people wearing white gloves.

I mean, they say you die twice. One time when you stop breathing and a second time, a bit later on, when somebody says your name for the last time.

I don’t know why people are so keen to put the details of their private life in public; they forget that invisibility is a superpower.

The bad artists imitate, the great artists steal.

I like to think I have the guts to stand up anonymously in a western democracy and call for things no-one else believes in – like peace and justice and freedom.

Nobody ever listened to me until they didn’t know who I was

There’s nothing more dangerous than someone who wants to make the world a better place.

Nothing in the world is more common than unsuccessful people with talent, leave the house before you find something worth staying in for.

I just wanna make the world a better-looking place. If you don’t like it, you can paint over it!

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.

Graffiti is one of the few tools you have if you have almost nothing.

Fight the fighters, not their wars.

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.

People say graffiti is ugly, irresponsible and childish… but that’s only if it’s done properly.

Speak softly, but carry a big can of paint.

I don’t think you should have to pay to look at graffiti. You should only pay if you want to get rid of it.

Graffiti is only dangerous in the mind of three types of people; politicians, advertising executives and graffiti writers.

Is graffiti art or vandalism? That word has a lot of negative connotations and it alienates people, so no, I don’t like to use the word ‘art’ at all.

Writing graffiti is about the most honest way you can be an artist. It takes no money to do it, you don’t need an education to understand it, and there’s no admission fee.
