A Cozy Hut for Grammarnazi

Does FOMO only occur for the need of the latest brand?

FOMO is fear of missing out. But people often associate with material things. Meanwhile, I'm also feeling the fear of missing out not on the new brand or trend, but on productive achievement. If my friend joins a new youth organization, I will go frantic and also search for the same. If my friend joins a volunteer, I will also join a volunteer. If my friend joins a competition, I will hastily force myself to join one. All of those without me being passionate about it. I don't actually want it. I'm just FOMO.
