They generally do not expect to be successful. They often put themselves down and tend to discount or ignore compliments paid to them. By contrast, self-confident people are willing to risk the disapproval of others because they generally trust their own abilities. Self-confidence is not necessarily a general characteristic which pervades all aspects of a person's life. Typically individuals will have some areas of their lives where they feel quite confident, e.g., academics, athletics, while at the same time they do not feel at all confident in other areas, e.g., personal appearance, social relationships.
Many factors affect the development of self-confidence.
Parents' attitudes are crucial to children's feelings about themselves, particularly in children's early years. When parents provide acceptance, children receive a solid foundation for good feelings about themselves. If one or both parents are excessively critical or demanding, or if they are overprotective and discourage moves toward independence, children may come to believe that they are incapable, inadequate, or inferior. Students in their college years reexamine values and develop their own identities and thus are particularly vulnerable to the influence of friends. It is more realistic and desirable to develop personal standards and values that are not completely dependent on the approval of others.
