It wasn't until she became an adult and a librarian, Nancy Pearl writes, that she "began to question my commitment to finishing each and every book that I began." Now she has a simple method for dropping a bad one, one obvious and plain and yet fair enough: the Rule of 50.
Give a book 50 pages. When you get to the bottom of Page 50, ask yourself if you're really liking the book. If you are, of course, then great, keep on reading. But if you're not, then put it down and look for another. (Always keep in mind that there's nothing to stop you from going back to it later, whether that might be in six days or six years. Or 60 years. There is many a book that I couldn't get into the first time, or even two, that I tried to read it, and then, giving it one more chance, totally fell under its spell. The book obviously hadn't changed – but I had.)
All my books will henceforth be 50 pages long, thereby obligating Nancy Pearl to read them in their entirety.
