““When Balzac was working, his writing schedule was brutal: He ate a light dinner at 6:00 P.M., then went to bed. At 1:00 A.M. he rose and sat down at his writing table for a seven-hour stretch of work. At 8:00 A.M. he allowed himself a ninety-minute nap; then, from 9:30 to 4:00, he resumed work, drinking cup after cup of black coffee. (According to one estimate, he drank as many as fifty cups a day.) At 4:00 P.M. Balzac took a walk, had a bath, and received visitors until 6:00, when the cycle started all over again.””
