Narcissism has two meanings: 1) Based on a Greek myth about a man who fell in love with his own reflection and drowned, his mother named the flower that grew in his place "Narcissus". 2) Being totally self-absorbed, vain, and self-obsessed. Narcissism can be bad if taken to an extreme, as people may become too focused on themselves and disconnected from others. To improve, people should love themselves but remain modest, humble, interested in others, considerate, and cooperative.
