Narcissistic Personality Disorder (a novella, sorry)

[Undertoad]

If you know you have a personality disorder, I think you are a little ahead of the game. Regardless of whether you can do anything about it without therapy.

I don't think NPD guy realizes his situation. I believe it is self-defeating in his case and will probably lead to a general downfall. The websites that discuss it, say that NPDs eventually wind up depressed or otherwise dysfunctional. What other outcome could there be, if they believe they are designed for success, and then the personality that tells them that makes it impossible. You can't be the boss if people don't want to work for you.

I think we can only escape our personality quirks, however we want to describe them, through years of therapy where we're actively working on it, or medications that slowly retrain our brains to different patterns. Someone who is PTSD has had their brain trained to react to repeated stresses - but over time it can be retrained to not react that way.
