In Greek mythology, Narcissus fell in love with his own reflection in a pool of water. Transfixed by his own beauty, he sat at the water’s edge staring at his own face until he died. The story of Narcissus is where we get the term “narcissism” — a personality trait hallmarked by arrogance, selfishness, and vanity.
We’ve all known a narcissist or two — the ones who think they are God’s gift to the Earth, who need all of the attention all the time, who believe they’re entitled to special treatment and favors. Narcissists can be arrogant and boastful, and they feed off of the admiration of others. People with narcissistic personality disorder have a mental health condition that takes all of this to an extreme. But it’s common to find narcissistic traits among otherwise healthy people.
