Leadership, for whatever profession, politics, business, education or goverment, is vitial important. The effectiveness and wisdom of leaders, who make decisions and direct the development of the groups, lay the foundation for the success of any enterprise. One approach to ensure revitalization of an organization is to require those in positions of power to step down after a certain period of service. However, this is not the surest path to success, since, under certain situations, it may impose damaging effects.

The advantages that those in power should step down every five years or so is evident. First, it is an effective way to prevent corruptions, which are usually caused by the long-time holding of privileges and the lack of supervising. Such cases are not rare in bussinesses, and are even common in politics. Goverment officials, in many countries, use their power for their own profits rather than solving several social problems and improving people's lives. Another advantage is to eliminate biases in the eye's of leaders. Leaders are humans, and are also tend to view things from their own perspective. And such biases usually cause problems since biased decisions are much more harmful than biased personal views - they may cause damaning effects on a large numer of people. Also, the alternation between leaders in a timely manner can invite competitions and provide new leaders, who often come up with new ways of taking actions and thinking, with equal opportunities.

However, the side-effects of leadership changes can not be neglected. Frequently changing leaderships, far too often undermines consistency of govermental policies and business strategies, and shake confidence of group members. Under critical situations, such as warfare, economical and political recessions, the stability of leaderships plays an critical role and is the key to guarantee the suviral of an enterprise. Considering the example of George Washington, the father of United States, who ran for a second time in office, mainly because of the perticular affairs that the nation are involved with, at that time. Furthermore, without a constant committment of leadership, the efficiency of an organization will be affected: good policies and practices may not be followed by successors; new leaders lack experience and ability to handle complex problems. Apple is such an example that demostrates the important of constant leadership.

In conclustion, the reasonability of alternating leaderships after a certain period depends on actual situations: fast social changes, too long, out-of-step, fail. Stability, too short, social problems.

E: tradeoff, changes, stability, experience and insights, new ideas and ways.
