1. You’re an idiot. You know nothing about books. You’ve only read comic books or Sweet Valley High up until now. You may think you don’t like real books, like Les Miserables, but if forced to finish one, you’ll realize the true value of literature! You’re not in a position to evaluate the worth of books yet; just finish them and ask questions later.
2. The main reason to read novels is for the plot. You may think you don’t like a book, but there could be a killer plot twist at the end that makes you see the value of the beginning of the novel in retrospect. Also you might miss something incredible. Don’t worry about the incredible stuff you might miss in books you haven’t started. If you haven’t started the book, it doesn’t count.
3. All books have inherent value. Don’t worry about the supposedly better books you could be reading instead (grass is always greener!); whatever book you have recently, arbitrarily started is, in the end, just as good as any other book.
4. Finishing novels teaches strength. You’ll prove to yourself that you can do it. If you don’t finish every novel you start, you have probably never finished a book and are probably also the type to eat all the marshmallows.
5. Whoever wrote the book finished it. It upsets the sense of symmetry in the universe if the writer finished it and the reader does not.
