I just did this. Turned the entire thing off so I have no youtube recommendations anymore, and then made sure I was subscribed to everyone I do enjoy watching (like 100+ channels). So now I just watch the same like 5 videos I actually wanted to watch that day, but without the garbage I wasn't going to like anyway. I don't think we realize how much the endless scrolling robs us of time and energy to enjoy the things we actually like.
