I don't believe the statement "narcissists are not self-aware". It's like any disorder - such as heath issues for example, where you are not expected to realise whats going on unless you research into it or talk to people who have experience with it.

Sam Vankin (the guy in the video) has wrote very detailed analysis of narcissistic experiences which are amazing reads and really help nail points down that one may have been wondering for a long time.

A self-aware narcissist is the first step forward in trying to make sure you don't hurt those around you. Most narcissists are intelligent and will be able to look at the "disorder" with an open mind. You start to truly reveal to yourself and understand your flaws and your strengths, and starts you on a journey of some soul-searching.
