All graffiti is low-level dissent, but stencils have an extra history. They've been used to start revolutions and to stop wars

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.

People who get up early in the morning cause war, death and famine.

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

Not everyone will understand your journey. That's okay. You're here to live your life, not to make everyone understand.

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

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