Lemmy really helps. Lot smaller then other places and not the engagement engineering. If it is really important national or global news someone will post it here too.
Use RSS feeds if you want more than Lemmy.
Bookmark then read. Review the bookmarks ruthlessly and only read stuff that is actually going to give you information related to you and actions you will take. Other stuff is just noise. Great example, I rarely look at stuff about Trump now. I know him and his minions, where I stand, and what my actions are… no more info needed on my end.
Have some perspective. Human history over the long span has been a story of improvement. We however live in interesting times.
Live you life best you can on your own terms. Does no one any good to do otherwise.
