We also have to be able to discern the difference between narcissism and marketing.
By marketing it can appear to be narcissistic when in fact it's not.
But marketing any individual in any field is has to be focused and narcissistic looking.
That's why we often come to hate overly marketed singers and movie stars so much. "oh they're so full of themselves"....
But sadly the more narcissistic one is, or becomes, very often the more financially successful or powerful (see politician) they become. Because they have a drive to be noticed. An overpowering need to be praised or loved (??).
This world ain't no meritocracy baby.
