Not a New Years' resolution, but a thing I've been doing for my own mental health since August is to stop following the news too closely. It's a large part of why I'm not really posting/reading here as much. I've deactivated my twitter account, I'm looking at news less, I've removed all social media from my phone, and I'm trying to spend more time looking/thinking about things I can impact/control, not just depressing news that I can't do anything about.
Also, the "polls" side I just don't care about when an election is 4 years away. It's not news, it's just attempting to sport-ify politics. Instead I've started watching actual sport a bit more where I can disconnect from it the next day.
I'll be happy with them as well.
Generally speaking I hope the 'big act show early enough to make the forum headliner' will become a tradition and not a one time thing
