" Anthony Trollope believed it unnecessary—and inadvisable—to write for more than three hours a day. He became one of the greatest and most prolific novelists in history while holding a full-time job with the British Post Office. He would rise at five-thirty, fortify himself with coffee, and spend a half hour reading the previous day’s work to get himself in the right voice. Then he would write for two and a half hours, monitoring the time with a watch placed on the table. He forced himself to produce one page of 250 words every quarter hour. "
