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

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

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

Imagine a city where graffiti wasn't illegal, a city where everybody could draw whatever they liked. Where every street was awash with a million colours and little phrases. Where standing at a bus stop was never boring. A city that felt like a party where everyone was invited, not just the estate agents and barons of big business. Imagine a city like that and stop leaning against the wall - it's wet.

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

You owe the companies nothing. You especially don't owe them any courtesy. They have re-arranged the world to put themselves in front of you. They never asked for your permission, don't even start asking for theirs.

Art is not like other culture because its success is not made by its audience. The public fill concert halls and cinemas every day, we read novels by the millions, and buy records by the billions. 'We the people' affect the making and quality of most of our culture, but not our art.
