Recently I became aware of how much time I was spending on YT and this is something that made a huge difference for me, I turned of all history and all recommendations and everything that I could turn off (don’t remember all the details)
After that I cleaned up all of my subscriptions so I was subscribed to only what I wanted and enabled notifications on all my subs.
What that did is that I no longer see any new videos at youtube, the main page NEVER changes except when there are new videos from my subs. So, I’d start browsing YouTube and actually get bored of it!!
Nowadays I only check it every other day and watch 3-5 videos of the people I follow, and after that there’s nothing else to watch, and I love it that way!!
Anyways, hope this helps!
