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

I’d been painting rats for three years before someone said ‘that’s clever it’s an anagram of art’ and I had to pretend I’d known that all along.

If you feel dirty, insignificant or unloved, then rats are a good role model. They exist without permission, they have no respect for the hierarchy of society, and they have sex 50 times a day.

If you don’t own a train company then you go and paint on one instead… it all comes from that thing at school when you had to have name tags in the back of something… that makes it belong to you. You can own half the city by scribbling your name over it.

I originally set out to try and save the world, but now I’m not sure I like it enough.

The greatest crimes in the world are not committed by people breaking the rules but by people following the rules. It’s people who follow orders that drop bombs and massacre villages.

Become good at cheating and you never need to become good at anything else.

I love the way capitalism finds a place – even for its enemies.

The grumpier you are, the more assholes you meet.

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.

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

I love the way capitalism finds a place – even for its enemies.

Nothing is black and white, and there is no purity and there is no such thing has justice.

Film is incredibly democratic and accessible, it’s probably the best option if you actually want to change the world, not just re-decorate it.

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.

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 have a theory that you can make any sentence seem profound by writing the name of a dead philosopher at the end of it.

I’ve always argued that this country has benefited immensely from the fact that we draw people from all over the world.

Excessive optimism shows the seeds of its own reversal in the form of imbalances that tend to grow over time.

Your family immigrated to this country – whether they came over on the Mayflower or whether they came over on a raft last year.

Over the years Miss Shepherd was visited by a succession of social workers so the character in the play is a composite figure.

I’ve bought QPP shares but unfortunately both times I bought it they immediately dropped by over 10p.

What we have found over the years in the marketplace is that derivatives have been an extraordinarily useful vehicle to transfer risk from those who shouldn’t be taking it to those who are willing to and are capable of doing so.

Someone’s always calling for my resignation. It’s nothing new.

It’s something that’s been part of my tenure at Exodus over the last decade plus.
