Any small room with no natural light will do. As for when, I have no particular schedules...afternoons are best, but I’m too lethargic for any real regime. When I’m in the flow of something I can do a regular 9 to 5; when I don’t know where I’m going with an idea, I’m lucky if I do two hours of productive work. There is nothing more off-putting to a would-be novelist to hear about how so-and-so wakes up at four in the a.m, walks the dog, drinks three liters of black coffee and then writes 3,000 words a day, or that some other asshole only works half an hour every two weeks, does fifty press-ups and stands on his head before and after the "creative moment." I remember reading that kind of stuff in profiles…and becoming convinced everything I was doing was wrong. What’s the American phrase? If it ain’t broke... ZADIE SMITH
