Most authors make the mistake of drumming up business (as if they were sign twirlers standing on the corner), when they (and you) should be creating an incredible longing, a passion for what you do, a tribe so enthused they sell your book for you.
Stop drumming and start dancing! You know the longing that made you want to write your book and share it with the world. Pass on that longing. Stop selling. Start leading the way!
