Confidence refers to one's feelings of self-worth and competence. Having moderate confidence can positively impact motivation and well-being, while very high or low confidence can be detrimental. Confidence is influenced by both internal factors like genetics and thoughts patterns as well as external experiences from relationships and life events. Maintaining a balanced, realistic view of oneself is important for solid confidence, while low confidence is associated with focusing on weaknesses, difficulty expressing needs, and negative perspectives. Steps to improve confidence include becoming aware of negative thoughts, challenging distortions, using positive self-talk, and practicing self-acceptance.
