what are the differences between leaders and managers?

The term manager typifies the more structured, controlled,
analytical, orderly, and rule-oriented end of the continuum. The leader end of the
continuum connotes a more experimental, visionary, unstructured, flexible, and
impassioned side.

Managers and leaders are not the same.
They think differently internally, and behave differently
externally.

In truth, leaders and managers tend to see different
aspects of work and organizational life as important, and therefore, worthy of their
time. They tend to treat people differently, and they spontaneously react to others
differently. They tend to allow their people to have different focuses, and to limit
their people in different ways.

Leadership is
defined as the act of arousing, engaging, and satisfying the motives of followers-in an
environment of conflict, competition, or change-that results in the followers taking a
course of action toward a mutually shared vision.
