To me, the most difficult part about quitting youtube, twitter or reddit is that these websites are incredibly rewarding and an incredible waste of time at the same time. Reddit has great discussions on careers, hobbies, whatever you do not stumble upon elsewhere, but the rewarding content unfortunately always comes in packs with some mindless scrolling and mediocre memes – I've never managed to have one without the other. Quitting them means to forfeit a huge, valuable chunk of input and I am yet not sure what's better.
