Writing is about culture and should be about everything. That's what makes it what it is.

If I don't have something to do, I'm not the kind of person who can sit on a beach on holiday. I've got to go and check things out and see things and look at things, and have some kind of itinerary in my mind. I think that a lot of people who are, in some ways, successful are kind of like that.

We have to concentrate back on: Where is the money going? Where's it been going for the last thirty years? How do we start to redistribute the cake more evenly, and give people opportunities? That's as much about poor white people in West Virginia as it is about poor black people on the Southside of Chicago.

People even split up by text message, they dump each other by text. Everything seems so disposable, so throwaway, but you have to engage with that if you're writing about the modern world.

The first of the Trainspotting crew to die. Out of the five of them like, Begbie, Renton, Spud, Sick Boy and [Margaret] Thatcher. Who'd have thunk she'd have been the first to go?

I spend so much time on the screen when I am writing, the last thing you want to do is spend more time on the Internet looking at a screen. That's what I hate about all this technology.

You've got first-generation Americans here who are going to be poorer than their parents. That's never happened in the States before, and it's going to have massive social repercussions here.
