Managers know what to do leaders inspire people to do it. The person who gets results through others is the one who is a leader, not a driver. Having people on your staff who "want" to do the things necessary to win is the consequence of leadership.
People often do things reluctantly when they feel forced into it. For a leader, someone who creates a culture of inclusion, expectation of excellence and appreciation, people will do their jobs enthusiastically and then some. Creating this type of work environment is much more a skilled and subtle process than "selling" your staff on an idea or process.

This type of culture in the workplace takes a leader who has studied his people, their motives and attitudes, which become these leaders' tools to help lead people to accomplishment. For many, security is the main drive to grow in their work and they are engaged when their work is viewed as important and they feel that their contribution matters.
