Leadership is the process by which a person influences others to accomplish an objective and directs an organization towards a common goal. It involves developing a vision that motivates people and creating a way for people to contribute to extraordinary outcomes. Effective leadership requires understanding human nature, needs, emotions and motivation. The leader must gain the followers' trust by convincing them of their abilities, and communicate through actions like leading by example. Different leadership styles are appropriate for different situations, including autocratic, participative, and delegative approaches.
