In the process of self-discovery, identity is a hidden treasure. "Become what you are!" is the platonic definition of identity. The Existentialist definition of identity has it that you are what you become (what you make of yourself). What you do defines yourself. Your mind is a blank sheet of paper (tabula rasa), written during your lifetime. In Exupery's story, "The Little Prince," we come across "become what you are," i.e. become child-like again.
