Lack of Confidence

Your degree of confidence, called self-confidence, is the trust or faith that you have in yourself and your abilities.  Self-esteem is the opinion you have of yourself.

Realistic feelings of confidence and positive self-esteem affect how you think and act, how you feel about others, and how successful you are in life.  Having self-confidence does not mean that you can do everything. Self-confident people have expectations that are realistic. Even when some of their expectations are not met, they continue to be positive and to accept themselves.
