I would say that I have the grandiose sense of self, partial lack of empathy and slight emotional stunting, and injury/rage/reaction cycle, but I would not consider myself interpersonally exploitive as I rarely lie or use underhanded manipulation tactics to get my way. Is this required to be one, or could this be a possibility?
More importantly, could it be just Aspergers? You decide!
I think if you are questioning if you have NPD then you probably don’t have it - most narcissists are not the most self aware or self reflective individuals and it wouldn’t occur to them to question their own behaviour
Unless the question was asked with the assumption that we'd validate it not being the case after some sort of prior narc wounding.

Do you have a job, do you feel comfortable with your life, and do you keep up with your upkeeps and collateral damages?
Yeah, I have a job. I do enjoy life at the moment. I am not the best with keeping up with people from the past but clearly neither are they though so I don't sweat it.
So far you sound functional then.
Collateral damages though? Do you leave any cinders in your wake or do you err towards "leave no footprints"?

Also, you pay a lot of attention to other people here. You often make posts involving other people. You are not the obvious self-absorbed kind of narc anyway.
