I put myself into a news bubble about six weeks ago. I still very occasionally read local news and a mainstream front page (say, every few days), which seems sufficient to let me know what's going on in broad terms. Stuff leaks into the bubble (e.g., via HN) but the point is not to be totally isolated, just not to get caught in hours-long doom spirals.

I've given money to the campaigns that are going to get money from me. I voted yesterday (which answered the question, "are we going to get our mail-in ballots on time?"). I'm done.

As a consequence I'm getting more done and I'm happier. I'm reading a lot more books.
