This article proposes a reflection on the youth ideal in the present world from the emergence of the new subject form in the contemporaneity: "cause of itself", marked by the maximization of the autonomy and freedom values. This subject-form makes itself without a collective enunciator, what point to an apparent self-sufficient condition. However, this new subject also hides a state of helplessness and abandonment. In this context, the new subject believes to be free from determinations, open to all ways and always willing to start over. Faced with the social imposition of multiple performances and flexibility, characteristics of contemporaneity, reaching maturity is no longer an ideal to attain, and remain young became the way that best answers to the constant capacity to reinvention of itself. Thus, in the current world in which everything can be tried at the same time as nothing should be permanent, being young has become a lifestyle.
