An author needs a lot more than one person to succumb to his literary seductive charms, but, like Saul, he must realize that he doesn't have to--and indeed cannot--capture the hearts of every possible reader out there. No matter who the writer, his ideal intended audience is only a small faction of all the living readers. Name the most widely read authors you can think of--from Shakespeare, Austen, and Dickens to Robert Waller, Stephen King, and J.K. Rowling--and the immense majority of book-buyers out there actively decline to read them.
