Self confidence means a firm belief in one’s qualities, competencies and credentials. Self confidence is a prerequisite for success. You need to believe in yourself to achieve and realise your goals. One needs to be sanguine about one’s chances of success and have extreme faith in one’s abilities. Confidence in one’s self is an indication of how positive one thinks. Optimistic people always view the glass as half full rather than viewing it as half empty. Even if adversities surround them, they never give up and always stay sure about their chances of success. A self-confident person always keeps his chin up in testing circumstances and is ready to take everything in his stride. Vivica Fox had once remarked, “A great figure or physique is nice, but it's self-confidence that makes someone really sexy.” So, it is. Self confidence adds to your personality and makes you look radiant and charming.
