ABSTRACT
There have been almost as many leadership theories and models as authors who have written on the subject. This chapter aims at integrating as much as possible that is of value into an overall leadership approach. One way to resolve the puzzle of leadership is to simply insist that the way one has defined and measured leadership is the correct and only way to do so. Leaders establish trust by taking actions that are consistent both over time and with what the leader has said. Leaders must also be sure to follow through on commitments, to do what they say they will do. Beliefs concerning change and adaptation are the organizational analog of self-confidence, the belief that one's destiny is a matter of internal control. Leadership involves the will to act, to use power in a positive or prosocial manner, and to think through the consequences of actions, over time.
