I feel you on the focus challenge -- my heroin is twitter, which I struggle to not read compulsively. (Right now I'm in a "delete my account" phase, but I know I'll go back.)
But for whatever reason, YouTube and TikTok are both very easy for me to consume in small amounts, deliberately.
Perhaps the thing I love most on YouTube is music. I've discovered so much great stuff there. But I'm sure there's more, if I only knew about it!
Beyond music, tons of other weird and/or life-enriching stuffL An old documentary on spanish gypsies. How to make an omlette. Programming live streams. Surreal russian war movies. Old Hunter Thompson interviews. Etc. etc. etc.
But mostly the new stuff I find these days doesn't come from YouTube reccs (which tend to just repeat the same things over and over, or show mainstream fluff, more akin to advertising than a personalized recommendation), but off-site sources, like blogs or twitter links. Which is a shame!
(Sort of tangentially, if I had to restart civilization from scratch and got to pick one single source of information to use, I'd pick YouTube for sure. I just wish Google were a better steward of that rather remarkable collection. (They really seem to be on a vendetta against the "You" part of YouTube...))
