Faced with an impossible time frame, he adopted a radical approach to making change. If there is one profession that owes its existence to the new economy, it is the change artist. They are the business-school professors who pen prescriptive books about the latest change offering. And sometimes, they are the motivational speakers who stand up in front of corporate audiences and make passionate pleas for new beginnings and self-belief. Change artists come into town, offer their wisdom, collect their fees, and then head home, where they design more offerings, conduct more research, and pen more books.
