I've seen a lot of definitions. The one I like the best is, Leadership is the courage to ignite and sustain authentic action in one's self and in others.
Leadership is the ability to unlock people's potential to become better.
Many will recall that AFS used to provide leadership training at Annual Meetings and Division meetings. It was formerly conducted quite successfully by Paul Brouha, Dale Burkett, and Pam McClelland. Somehow, it got dropped from our agenda by the mid-1990s. There were other clear messages that AFS needed leadership training. It seems to me that if we can accomplish these goals, not only will AFS have more experienced leaders, these individuals will also gain experience to help them on their jobs.
