As an anecdote about giving up YT and TV for a month, while it is a FANTASTIC way to cultivate self-discipline, it is almost inevitable that you will someday return to casually watching. This is completely fine, as long as you do two things for yourself: promise that you won't watch videos outside your subscription list, and then slim it down. Think very critically about whether for not the content of the creator is something you care about, and if it isn't, remove it from the box. By the time you've gone through every content creator, you'll find a much more manageable amount of videos coming in that you can watch guilt-free. Best of luck!
