The most horrible thing about the largest majority of human beings consists in living without seriously asking oneself about one's life purpose or, even worst, blindly accepting most trivial explanations
When we don't ask ourselves who we are or just give it for granted, we don't live anymore, we become merely machine.
Hence, if you feel confused, with plenty of doubts, uncertain regarding who you are and why you are here, rejoice! This is a clear symptom that you are still alive. You are one of the few living human beings left in this world, an almost extinct species, a glimpse of hope for mankind.
