"A movement is marked by an attractive, clear, unifying vision for the future together with a strong set of values or beliefs. The content of the vision must be compelling and clear so that others can grasp it readily. It must not be so esoteric or difficult that only a handful of people can articulate it. Instead, it must be something that all members of the movement can understand and pass along to others. By contrast, "institutionalized" organizations are held together by rules, regulations, and procedures, not by a shared vision.
This unifying vision is so compelling that it takes pride of place. First, the vision leads to sacrificial commitment. Individuals put the vision ahead of their own interests and comfort. They are willing to work without high compensation, power, or perks. The satisfaction of realized goals is their main compensation. There is no more practical index of whether you have a movement or not. If the leader is making all the sacrifices, you don't."
