Self confidence refers to having a belief in one's own abilities. There are three types of self confidence: low self confidence which is governed by what others think; optimal self confidence which involves doing what you believe is right despite criticism; and over confidence which is an unrealistic presumption of one's abilities. Developing self confidence involves identifying and replacing negative thoughts with positive ones, having a supportive network, focusing on talents, and accepting compliments. The advantages of strong self confidence include greater happiness, freedom from doubt and anxiety, more motivation, and greater success.
