Overcome the Eight Barriers to Confidence - Rosabeth Moss Kanter - Harvard Business Review

"Confidence is an expectation of a positive outcome. It is not a personality trait; it is an assessment of a situation that sparks motivation. If you have confidence, you’re motivated to put in the effort, to invest the time and resources, and to persist in reaching the goal. It’s not confidence itself that produces success; it’s the investment and the effort."
