Right. The article could maybe be written a bit better, but it says right from the beginning that this is an article discussing NPD individuals. NPD individuals do a lot of things that highly overlap with what non-NPD individuals do. They are just much more harmful. In general, whenever you read about X personality disorder, you need to mentally qualify every statement of behavior with some variant of "to the extent of consistently/frequently causing self-harm or harm to others". Chiefly, the fact that you are concerned with acting narcissistic is a strong indicator that you likely would not be diagnosed with NPD. Like I said, acting narcasissitcally in a moment, lashing out when your ego/self-image is damaged, feeling insecure, wanting external validation - these are -all- normal human behaviors. Completely erasing these "faults" is... I think impossible. That said, one does not have to be a NPD to be an asshole. Every group will have different thresholds from "noticeable trend of behavior" and "a real actual problem". Self-reflection is always helpful.
