Self-efficacy is the perception we have of our ability to reach a goal. It's our confidence regarding whether we can succeed at a particular task. A great deal of research supports the premise that a leader's level of confidence in accomplishing what he or she sets out to do will critically determine the outcome.... Without a strong sense of self-efficacy, a leader will avoid challenges and give up easily when confronted with setbacks.
