People who are not self-confident depend excessively on the approval
of others in order to feel good about themselves. They tend to avoid
taking risks because they fear failure. 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. They tend to accept themselves; they don't
feel they have to conform in order to be accepted.
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.
