When Steve Jobs died in 2011, I read Walter Isaacson’s biography. Jobs’ aggressive pushing of vision, against resistance from co-workers and the marketplace, seemed key to Apple’s unprecedented impact. To a lean extremist, the Steve Jobs phenomenon is pretty confusing. My bias was to be adaptive to marketplace signal, not to ignore it. As someone with my own dreams of changing the world, I admired Steve Jobs. Yet, I espoused a doctrine that made his success unintelligible. In retrospect, I’m amazed by how long I lived with this contradiction.
