When I was writing for children, I was writing genre fiction. It was like making a good chair. However beautiful it looked, it needed four legs of the same length, it had to be the right height and it had to be comfortable.

I suffer depression only in the sense that I am a writer. We don't have proper jobs to go to. We are on our own all day. Show me a writer who doesn't get depressed: who has a completely stable mood. They'd be a garage mechanic or something.

Most adults, unlike most children, understand the difference between a book that will hold them spellbound for a rainy Sunday afternoon and a book that will put them in touch with a part of themselves they didn't even know existed.

At twenty life was like wrestling an octopus. Every moment mattered. At thirty it was a walk in the country. Most of the time your mind was somewhere else. By the time you got to seventy, it was probably like watching snooker on the telly.

...and there was nothing to do except to wait and to hurt.

With English literature, if you do a bit of shonky spelling, no one dies, but if you're half-way through a maths calculation and you stick in an extra zero, everything just crashes into the ravine.

If one book's done this well, you want to write another one that does just as well. There's that horror of the second novel that doesn't match up.
