I never wanted to write. I just wrote letters home from a kibbutz in Israel to reassure my parents that I was still alive and well fed and having a great time. They thought these letters were brilliant and sent them to a newspaper. So I became a writer by accident.

When I was younger, I avoided exercise or anything strenuous. I didn't even enjoy walking. As I got older, I spent so much time marking books or sitting at a desk writing that there was no room for exercise - not that I would have bothered anyway.

I couldn't have children, so that's the bad side. But compared to everything else I have, it's not all that terribly bad. I count my winners rather than my losers.

Success is not like a cake that needs to be divided. It's more like a heap of stones - a cairn. If someone is successful, they add a stone to the cairn. It gets very high and can be seen from all over the world. That's how I see it.

In my stories, whenever there's somebody wonderful and charming and bright and intelligent, that's me!

I'm getting better, happier, and nicer as I grow older, so I would be terrific in a couple of hundred years time.

If you write what you know about, you will always be on safe ground. I am very edgy and nervous about going into territories I know nothing about. That's why you don't find much high finance, group sex, or yachting parties in my stories.
