I enjoy the freedom of the blank page.

I think just getting up and getting to the desk is a big thing. If you can do that, you're in the zone because there're so many distractions that can stop you. From my bedroom to my office isn't really that far, but I have to go via the kitchen and there's so many things that can stop me and interrupt me.

When you think about what Homo sapiens are about, you almost feel that we are replacing ourselves. We won't be able to breathe and breed on this earth, so we replace ourselves with androids that can do. The androids can go up into space and take the future of humanity forward because maybe we just bow out with a carbon-based epoch.

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? She was the invisible author of the book, really. She created the conditions and the hubris whereby that whole culture flourished.

We start off with high hopes, then we bottle it. We realise that we’re all going to die, without really finding out the big answers. We develop all those long-winded ideas which just interpret the reality of our lives in different ways, without really extending our body of worthwhile knowledge, about the big things, the real things. Basically, we live a short disappointing life; and then we die. We fill up our lives with shite, things like careers and relationships to delude ourselves that it isn’t all totally pointless.

It was around the summer of 1982 when the drug problem really impacted. It became a lifestyle rather than a recreation. When you start lying and stealing, you cannot con yourself you're in control any more.

In civic life, I think that's where you can debate what is good taste and what is acceptable to other people, and what's gonna offend people. Do that there, but leave it out of art, because art is the one frontier that shouldn't have restraints put on it.
