It's so hard to create a fake identity -fake name, fake life, fake interests - a complete different person. Yet, what is even harder is put up the real identity to the public. But, what is the real identity? Who is the real true self? How can it be shaped?
It is impossible to show the real identity to everyone for there isn't any. It is well-controlled by the society. Sometimes, the real identity has certain orientations and practices that do not go well with the society's in which a person lives. The society disapproves these orientations and practices, even if there's nothing wrong with them religion-wise, and even if the society feels inside that they are okay! Hence, the true self and the real identity disappears and the person becomes soulless, aimless and completely lost just searching for true self.
We sometimes create "a true self" which is actually fake, and we adopt it for some time for a specific reason and perhaps a specific audience. Yet, this "true self" soon becomes so boring and unappealing. Then the true "true self" is provoked to appear and dominates the fake "true self."
Then, a moment of truth comes, and the person finds out that not reflecting or not living, or even feeling, the fake "true self", even in a fake world like the cyber space for example, gives a hard time and soon they should return to their own old selves.
When finding the true "true self", peace of mind and self-confidence come along with it. For the person will be their own true selves and they don't have to fake anything anymore. A person can only reach this level of true-self recognition when reaching maturity.
