One common characteristic of the great leaders I meet is self-confidence, which of course makes sense. Leaders have to inspire confidence in others. It would be difficult for others to believe in us if we don't even believe in ourselves.
Great leaders have to take risks. While getting to "acceptable" may not involve risk, getting to "one of a kind" does. Self-confidence gives great leaders the courage they need to take their companies—and themselves—to a new level of success.
