I ask because I used to think I was always right and others were wrong.

It all hinges on how I define success, ... If I was filthy rich playboy captain of industry I can see myself being an abusive NPD.  If on the other hand, my success is "not-so-much" then I am just a multiple failed relationship loser who is angry frustrated and bitter.

So the cure for BPD is to become filthy rich! ... : )
