People are inspired and aroused by exciting images of a preferred future, principles or values that ring true, and being part of a higher cause or purpose that helps them feel they're making a difference. Like thermostats they try to set the temperature of their environment. Thermostat leaders work to define and create what could be rather than just reflecting is. Now if the furnace or air conditioner isn't working or all the windows have been left open, a thermostat might not be able to change the room's temperature. But it still tries.
Goals are management issues.
They deal with rational analysis, planning, measurement, and discipline. Visions are leadership issues. They deal with feelings, energy, ideas, and fantasy. I've also seen too many key managers fail to act like leaders. Highly effective organizations are brimming over with leaders at all levels and in all positions.
