If you want to be more confident, look inward. Confidence is a belief in an outcome, and therefore is an emotion put into action. When you believe in something, your actions match that belief. Telling yourself the truth helps define your beliefs. Beliefs can change, truth doesn’t. Truth is constant. Confidence is based on belief, not on truth. Tell yourself the story you want to become reality and your belief will adjust and your actions will create the desired result.
