narcissist

n. one who admires oneself; one who is in love with oneself

Narcissism describes the character trait of self love. The word is derived from a Greek myth. Narcissus was a handsome Greek youth who rejected the desperate advances of the nymph Echo. As punishment, he was doomed to fall in love with his own reflection in a pool of water. Unable to consummate his love, Narcissus pined away and changed into the flower that bears his name, the narcissus.
