tell the difference between a servant leader and a self-serving leader? Gordon MacDonald, in his classic book Ordering your Private World,[2] gave us a good hint when he identified two kinds of people in the world: driven people and called people. Driven people think they own everything. They own their relationships. They own their possessions. They own their position. As a result, they spend most of their time protecting what they own. Everything they do is determined by their own self-interest.
