One of the secrets of the book-writing business is how few people read books. This is especially true of literary books. Like, if the NYT bestseller list were stripped of celeb books, self-help books, and "beach reads," I bet you could get on with fewer than 500 sales per week. Maybe fewer than 300. It's astonishing to read what publishing was like about 100 years ago before mass media, when regular people would buy the Saturday Evening Post for original short stories.
