FOMO is a psyop you do against yourself.
Following along with the corporate media, each day is like a new chapter in a trashy thriller novel. Always another fresh outrage, phantom menace, or impending doom to talk about. You end up talking about the newest thing around the water cooler, just like you could talk about the latest episode of Breaking Bad.
It's a literal reality TV.
99% of the daily narrative is completely irrelevant to your life, yet you're investing mental energy and time into it. The more time I spend away from it, the more I notice just how little I miss out on by not paying attention to it.
