The opening chapter introduces the purpose of leadership as moving the world. It is not about the leader, or the leader’s organization, but about making a positive change in the world. The power and potential along with the danger and horror of leadership is considered. A formula for work and leadership is proposed and Archimedes’ principle of the lever is introduced as a central organizing metaphor for the book and each part of the metaphor is explained along with the six basic assumptions of the book. These assumptions include the need for clear definitions, clear purpose, the importance of a leadership mindset, everyone taking on the call of leadership, and the critical need for leveraged leadership power to produce high performance.
