Adolescents may be, almost simultaneously, overconfident and riddled with fear. They are afraid of their overpowering feelings, oflosing control, of helplessness, of failure. Sometimes they act bold, to counteract their imperious yearnings to remain children. They are impulsive, impetuous, moody, disagreeable, overdemanding, underappreciative. If you don't understand them, remember, they don't understand themselves most of the time.
