I'm always skeptical when someone tells me about themselves. It isn't that I think they're lying. It's that one's self-appraisal is more often than not a representation of how they want to see themselves as opposed to an honest assessment.
The tale of Icarus and his wings of wax is one of the more famous classical myths. It tells of a talented Athenian craftsman named Daedalus who was trapped on the island of Crete with his son Icarus. Daedalus, you see, had built an unsolvable labyrinth to contain a beast called the Minotaur for the King of Crete near the King's palace in Knossos. When the King imprisoned the great hero Theseus in the Labyrinth to be killed by the Minotaur, Daedalus helped Theseus escape by giving him a special spool of string. For this, Daedalus and his son Icarus were themselves imprisoned within the Labyrinth.
We have a shadow, says Jung. A reservoir for human darkness. A place where everything we choose not to accept about ourselves exists. Whether we acknowledge it or not, it is buried behind all the desirable aspects of our psyche. It is our 'dark side', trained and caged by societal and cultural norms. But every once in awhile, we see it manifest itself. We see it rear its ugly head.
