I realize that most authors would talk about how to make the idea before they teach you how to sell it. That’s backward. Knowing how to sell your idea - make it happen - is the step you must take before you bother inventing it. If you can’t figure out how to implment your idea, there’s no point in inventing it, is there? If you insists on reading section 3 [Creating the Free Prize] first, it won’t kill you, but I really wanted to hammer home the idea that you need to learn how to sell something before you focus on what to make.
Seth Godin, Free Prize Inside: The Next Big Marketing Idea, 2004, p. 57, emphasizing again that marketing is all that matters.
