Writing a novel- actually picking the words and filling in paragraphs- is a tremendous pain in the ass. Now that TV's so good and the Internet is an endless forest of distraction, it's damn near impossible. That should be taken into account when ranking the all-time greats. Somebody like Charles Dickens, for example, who had nothing better to do except eat mutton and attend public hangings, should get very little credit.
