Get over yourself. Learn to at least respect the interests of others even if you can’t appreciate them. And above all, never imagine for one second that the intensity of your self-absorption escapes the notice of others.
For some reason, presumably their complete lack of empathy, narcissists of both sexes and all SSH ranks appear to believe their comprehensive self-absorption is invisible to others. Even the most harmless and least offensive form, Delta narcissism, is completely obvious once you’ve recognized the pattern.
I always find it amusing when a Delta informs me that he doesn’t care about the overall mission, what anyone else thinks about his job, or anyone else’s responsibilities. I never know what to say, because it’s like someone telling you that water is wet. “Yes, I know you don’t care about anything but your one task at hand, that’s literally what narcissism is.”
