"Once they reached this stage the adolescents start to search for a new identity and during this search they are often confronted with confusion and a lot of contradictions within themselves. There are coexisting two personalities. One is the 'child' and the other one the 'adult' and both change their character in a way that is unpredictable and absolutely unexpected. But the adolescents also feel great passions to devote themselves to their ideals, being more and more capable to criticise the traditional ideals and develop their own ones. The young are always thirsty for individual space and freedom. As they evolve they realize what it means to be an adult and start to take on, among other things, the responsibility for their own actions. However, the adolescents are troubled by self-doubts and cannot stop to find out everything about their identity".
