The word "narcissism" derives from an ancient Greek myth. In it, the young Narcissus, widely known for his great beauty, rejects the love of the nymph Echo. This angers the gods who curse Narcissus, ensuring that he could only love himself. He gazed at his reflection in the still waters of a pond until he died—either from lack of care or by his own hand, depending on the version. If you're wondering what the difference between narcissistic behavior and full-blown pathological narcissism is, listen to this episode to find out.
