“I find it’s more fun to write about something that you don’t know completely and that you will discover on route. A dear friend of mine...once said: 'The only time I know anything is when it comes to me at the point of my pen.' So I think that if you start to write about things that you know half well, that you’re fascinated by, that you sense you have an appreciation of that others might not have, but you do have to acquire the knowledge as you go, you discover a great many things at the point of a pen. And it keeps the writing alive in itself in a way.
