Self-confidence is a belief in oneself, one’s abilities, or one’s judgment. It is freedom from doubt. When you believe you can change things — or make a difference in a situation, you are much more likely to succeed.
As a self-confident person, you walk with a bounce in your step. You can control your thoughts and emotions and influence others. You are more prepared to tackle everyday challenges and recover from setbacks. This all leads to a greater degree of optimism and life satisfaction.
