The thing that helped me tame YouTube was creating separate channels for my various interests. This keeps all my relevant subs in one place and really helps the algorithm. I turn off all the feeds on my main computer using https://socialfocus.app/. This prevents me from going down a YouTube hole when I don't want to but my searches and views still tune the respective algorithms. Occasionally, a stray recommendation will show up in the feed and I try to mark it "Not Interested".
Now its a real joy checking my channel feeds on the weekend and queueing things up to watch later. I have excellent stuff to chew through when I feel like it - in the gym, cooking, cleaning etc. I really look forward to doing these things now.
Switching profiles takes a few clicks but the upside has been totally worth it. It's a shame they don't make this workflow more obvious (You have to go to Account -> Switch accounts -> View all channels -> Create a channel) to set this up.
I wish more social media allowed you to bucket your feed into "interests". Maximizing clicks/views doesn't have to come at the cost of scattered attention.
