There are many, many types of books in the world, which makes good sense, because there are many, many types of people, and everybody wants to read something different. For instance, people who hate stories in which terrible things happen to small children should put this book down immediately. But one type of book that practically no one likes to read is a book about the law. Books about the law are notorious for being very long, very dull, and very difficult to read. This is one reason many lawyers make heaps of money. The money is an incentive - the word "incentive" here means "an offered reward to persuade you to do something you don't want to do" - to read long, dull, and difficult books.
