I generally just don't care enough about what happens in the world anymore, though this particular quake is really terrible of course. But there's nothing I can do about it.
Just once a day or so I might check the local newspaper website, for things that might affect me. Which is where I heard about it because something this big will make the front page even there.
But generally I don't miss the world news at all, I don't feel FOMO or less informed. I'm not a boring person either IMO, I just like being active in tech and the creative (maker) community, with things I can actually influence. I'm very interested in people I meet. It's more about taking control of information.
I do the same with instant messaging. I can be quite active but only on my terms. All my group chats are muted, and all but the most important people too. I'll see your messages eventually but when it suits me. If it was urgent you'd have called anyway.
It's good to know about this band assignment though as I'm also a HAM operator. But I don't use the 10m band that this frequency is on anyway.
Staying informed is good, but there are relatively small number of things that need a reaction in real-time. Eventual consistency is sufficient, and frees cognitive cycles for things I have immediate influence over.
