Mark Twains litmus test for marketing & advertising success
But the man whom I most depend upon is the man who always goes to sleep. If he drops off within 15 minutes, I burn the book. If he keeps awake three quarters of an hour, I publish, and I publish with the greatest confidence, too. For the intent of my books is to entertain and by making this man confortable on a sofa and timing him, I can tell, within a shade or two, what degrees of success Iâ€™m going to achieve.â€ ~Mark Twain
