Adolescence is considered a period in person's existence and the evolution of his / her personality, it is the age that shocked all the time creating sometimes social conflicts and anxieties. In adolescence there is a desire to affirm, to identify the self with patterns of independent behavior that precede the stable definition of one's own personality. The widening of the sphere of social experience determines the harmonization of skills and attitudes with social requirements and greatly develops the critical and self-critical spirit. But the process of identifying and developing self-consciousness also involves reporting to those of the same generation, to the same age group. If the adolescent has a higher self-consciousness than the way he is evaluated by others, he will feel isolated, trying to find expressions of his own to bring admiration and acceptance to others. This explains terifism, stubborn and oppositional manifestations, originality crises, and sometimes even delinquency. In their turn, adolescents with a superior self-esteem and well-accepted by colleagues present trust-based behaviors, strongly support and argue their opinions, have fewer personal problems, more easily overcome difficulties, and are more inclined towards their own initiatives.
