A Leader LEADS his organisation to a certain point. His most important task is to define this point, to communicate and promote it, and to onboard his people on the journey to this point.
Good leaders usually have a clear picture, a vision, about what that point looks like. He ‘sees’ how the children of former slaves and former slaveholders will sit together on the same table, or how the first man walks on the moon, or how cars will drive electrically.
A good leader is not is not necessarily a manager: as long as he surrounds him selves with people who can follow him and manage the process of change, he can successfully lead the organisation.
