Management teaches that power belongs in the hands of a few select 'leaders' at the top. A good leader's goal is to build an organization filled with leaders at all levels, not to surround himself with followers. Management teaches that excessive rules and controls are necessary to get the best out of followers. Leaders know the more they control others the less likely they are to excel. They understand the only reason you need excessive rules and controls is if you think people are either evil or stupid.
Management teaches that followers are there for the benefit of the bosses.
Leaders understand their job is to serve others, not to be served. It's the leader's job to add value to others, to sell themselves and their vision. Leaders seek long-term vitality for their organization, not quick fixes. Management focuses more on today and less on the future. Leaders spend more time charting the course than charting results, more time problem predicting than problem solving.
