While both leadership and management require near identical skills and abilities, what defines a leader and what defines a manager are two completely separate things.
As referred to by Robert I. Sutton in his post "Why "Big Picture Only" Bosses Are The Worst," “Managers are people who do things right and leaders are people who do the right things." Warren Bennis, the original writer of the quote, seems to imply that managers are willing to sacrifice and do any and all actions to reach their objectives, following the means of the end justifying the mean. Leaders on the other hand are more moral in their endeavours. Leaders are willing to sacrifice their goals to save their followers and any loyal parties that they may deal with. The manager puts themselves and their goals above their supporters while the leader places their follower's health above all else.
And just becuase one is a leader, doesn't mean they have to be a manager and vice versa a manager doesn't neccessarily mean they are leader material.
