“Advertising is like sprinting. You have 30 or 60 seconds to tell a story and make the same kind of emotional connection that a filmmaker builds over two hours. When you do make that connection with a patient, you know you've done something more important than sell Ginsu knives, you've set that person on a path that could change his or her life.”
