But while rhetoric can certainly inspire, we need to remember that concrete objectives have the power to elevate and inspire as well. A powerful essential intent inspires people partially because it is concrete enough to answer the question, "How will we know when we have succeeded?" ... the actor/social entrepreneur Brad Pitt, who, appalled by the lack of progress in rebuilding New Orleans after Hurricane Katrina, had started an organisation called "Make It Right" with the essential intent "to build 150 affordable, green, storm-resistant homes for families living in the Lower 9th Ward." That statement took the air out of the room. The concreteness of the objective made it real.
