Writing before dawn began as a necessity—I had small children when I first began to write and I needed to use the time before they said, “Mama”—and that was always around five in the morning. Many years later, after I stopped working at Random House, I just stayed at home for a couple of years. I discovered things about myself I had never thought about before.

Stay in your mental pyjamas all day. […] Work in the morning, a short break for lunch, work in the afternoon and then watch the six o’clock news and then go back to work until bed-time. Before bed, listen to Schubert, preferably some songs.

When I’m working on a novel I type the initial draft first thing in the morning. Really: first thing. For preference, I have a cigarette ready-rolled and a coffee percolator loaded the night before; then I simply roll out of bed, fuel up and set to it. I believe the dreaming and imagining faculties are closely related, such that wreathed in night-time visions I find it possible to suspend disbelief in the very act of making stuff up.

Our life here is simple, very simple. Get up in the morning, go for a run, come back. If it is a day for cleaning, we do the cleaning, or we just relax. Then go for lunch, massage, the 4 o'clock run, evening tea, relax, go to sleep. As simple as that.
