Narcissism is the pursuit of gratification from vanity or egotistic admiration of one's own attributes. The term originated from Greek mythology, where the young Narcissus fell in love with his own image reflected in a pool of water.
In general, synergy (pronounced SIN-ur-jee, from Greek sunergia, meaning cooperation, and also sunergos, meaning working together) is the combined working together of two or more parts of a system so that the combined effect is greater than the sum of the efforts of the parts.

Simply stated, synergy results when the whole is greater than the sum of the parts. For example, two people can move a heavy load more easily than the two working individually can each move their half of the load. Synergy can be a positive or negative outcome of combined efforts.
