A leader is someone who can enlist the aid and support of others to accomplish a common task through a process of social influence. There is no single approach to leadership, but effective leaders build mutual trust with others, are willing to learn and adjust to situations, and possess traits like intelligence and charisma. The role of a leader is to support a group in achieving its goal by setting goals, organizing work, and helping the team develop while providing freedom and support. Anyone can become a leader by taking action, learning from observation and experience over time, rather than relying on a formal position of authority alone.
