1. Leadership is "a process of social influence in which one person enlists the aid and support of others in accomplishing a common task". Management is "the act of getting people together to accomplish desired goals and objectives".
For a more in-depth look at management and leadership concepts, read Defining Leadership, and pay particular attention to the "Management versus Leadership" section.
2. Many people have very rigid concepts of managers and leaders: The former is results-oriented and concerned with internal tasks like scheduling, budgeting, controlling, etc. The latter is heroic and inspiring and focused on creating change in the world. Since the 1960s, social scientists have become more interested in studying leadership and the traits and behaviors common among effective leaders.
If you feel less confident in your ability to separate leadership and management, read What is Management? and focus on the "Management versus Leadership" section.
Think about the five common styles of leadership.
The five leadership styles originally posited by Kurt Lewin are examined in the Styles of Leadership. You may also want to brush up on Lombardi, Jobs, Mandela, or Roosevelt's leadership styles.
Some traits, when found in individuals, are highly predictive of strong leadership capacity. Zaccaro argued that effective leaders possess cognitive abilities, social capabilities, and dispositional tendencies. When most people think of traits, they think of a leader's character, but be sure not to overlook cognitive abilities and skills!
Zaccaro's model is discussed in Defining Leadership.
Part of leadership is innate to our person, but part of it comes from our environment.
