I've been doing the following for almost two months:
1) I do not read Facebook or Twitter at all, full stop. It was admittedly weird watching the Super Bowl without a "second" screen, but who cares.
2) I unfollowed almost everyone on Instagram and was left with about 75 people that I consider close friends/family friends or interests (e.g., the Cleveland Indians account). I can generally keep up with people on Instagram, and by design, it's way less bullshit than Facebook.
3) I customized Apple News so that it's basically 100% sports, law, and personal finance news. It's very nice, as it breaks things down into my interests (Ohio State Football, Cleveland Indians, Cleveland Browns, NFL, College Football, law, SCOTUS, etc.). I also had to work quite a bit to block every single news outlet on there, and any stories. So the NYT, WaPo, CNN, Politico, etc. are all blocked; and any story with Trump, Clinton, Pelosi, whoever is also blocked. I haven't seen a politics story in weeks.
4) The only news outlet I read is The Atlantic. I do not read the news or opinion articles, but I get the gist of what is going on. But, The Atlantic has excellent writing about science, culture, etc., and I become a better writer by reading. I think that's worth the minimal exposure to the news.
5) No nightly news. I see bits of the Today Show when my wife watches in the morning, but no nightly news.
I've only been doing this since Christmas, but it honestly has become habit at this point. I've read three books this year and just ordered three more from the library.
Now if only my diet and exercise resolution was going as good.
