Narcissism, then what?

I think I've successfully been able to wean off supply, and thus inadvertently dismantled the whole narcissism value system I've been coasting on. But then what?

I'm left with the question of why I should do anything, if I'm not pursuing supply. What else is there even? Every fucking thing in my life is set up to generate me maximal supply.

How do other people get motivated to do shit? How do other people get motivated to live their lives and not just off themselves?

There are the generic platitudes of "just do what you enjoy" or whatever the fuck, but how?
