Narcissism occurs when I begin to perceive myself to be an extension of everyone else, and as such, I falsely believe my feelings to be dependent on what occurs externally (outside of me). In plain English, I start to blame others for how I feel, which is delusional. By the way, it is also narcissistic when I start thinking others should think or feel the same way I do about something... so feel free to disagree.
But the point is, once again, that knowing all about our flaws is completely useless if we don't cleanse ourselves properly via inventory etc. so that the work we do actually works. This is why therapy is such a hoax. All talk, no action. Talking, reading and studying don't change people. Action does. Below is the original post, Change is Internal.
