Traditional graffiti writers have a bunch of rules they like to stick to, and good luck to them, but I didn't become a graffiti artist so I could have somebody else tell me what to do. If you're the type who gets sentimental about people scribbling over your stuff, I suggest graffiti is probably not the right hobby for you.

There's obviously nothing wrong with selling your art - only an idiot with a trust fund would tell you otherwise. But it's confusing to know how far you should take it.

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.

When he time comes to leave, just walk away quietly and don't make any fuss.

As far as I can tell the only thing worth looking at in most museums of art is all the schoolgirls on daytrips with the art departments.

Once upon a time there was a bear and a bee who lived in a wood and were the best of friends. All summer long the bee collected nectar from morning to night while the bear lay on his back basking in the long grass. When winter came the bear realised he had nothing to eat and thought to himself 'I hope that busy little bee will share some of his honey with me.' But the bee was nowhere to be found - he had died of a stress induced coronary disease.
