Very un-HN take but maybe you're not meant to be 100% efficient all the time, maybe having some time to be passive and relax is good actually. Maybe we work far too much already and expecting to be additionally productive outside those hours is an express train to burnout?
I don't disagree with this but the constant state of being "plugged in" is the issue. Mind wandering is a real useful practice and the being plugged in is antithetical to mind wandering.
Some of my most clearest thoughts, ideas, or beliefs came to me when I was just walking on the street not listening to podcasts, audio books, music or browsing social media.
I think it's far more useful to literally stare at a wall for 3 hours than just mindlessly watch youtube videos. I say this as someone who is addicted to social media/internet as well and struggle very hard to overcome.
What I do is use the freedom app to set time limits and ban these sites during periods of the week. I bought one of those timed safes where I stick my phone in to completely stop the temptation for 4 or 6 hours. I know I can't completely end it, but what I want to do is just nudge myself to do something else. Instead of grabbing a phone maybe I'll attempt to read a book, or draw, or work on some data visualizations, or contribute to OSS. All activities I'd say I value more than browsing reddit (or twitter or youtube or HN) for hours every night, but my actions prove otherwise.
I'm not saying I've improved my habits 300% but at the beginning of the year I would read a book for 5 minutes put the book down pick up my phone then read reddit for an hour; at least now I can read a book for 45 minutes without being distracted. It hurts writing this because in college I'd read nearly 500 pages a week + my readings for class, I'd read nearly 200 books a year but over the last 5 years I've probably read 3.
I don't know where I'm going with this, I guess my mind wanders when writing as well...
It sounds like you're already approaching this idea on your own, but if you haven't checked it out already you should have a look at Digital Minimalism [1]. It's a really well thought out analysis of exactly what you're describing. In theory, a few hours here and there shouldn't be an issue. However, the main problem with modern media (social and otherwise) is that it is very insidious. It's not just about the time spent indulging, but also what that indulgence does to your mental state throughout the rest of the day.
Thanks for the suggestion; but after reading one similar book, Stolen Focus by Johann Hari, and another that was tangentially related, Four Thousand Weeks by Oliver Burkeman. I now feel tapped out of the genre.
One thing I enjoyed about Four Thousand Weeks was the story how people viewed work 100s and thousands of years ago, how whatever you didn't finish that day, you had time tomorrow to continue; I think this is a useful idea because modern society feels so "rushed" over work that isn't exactly useful. Also the idea of JOMO (joy of missing out); it was just a new heuristic introduced to me. We make choices all the time, we neglect doing things all the time. It's just a part of life, missing out on things means enjoying others It sounds like it's more stressful but it's not, at least how the book describes this.
With Stolen Focus, I was a fan of the author's interview about his other book "Lost Connections" when he appeared on an episode of econtalk [1]. I won't say much else about Stolen Focus, except his tips on what he does to lessen the nodge toward social media is what I now do as well.
Instead of seeing them trying to maximize efficiency, think of them trying to maximize fulfillment. Now it makes more sense why binging Youtube (or whatever) might be a problem. And it's not about getting work done.
It's about being happy with the life you're living, the life you chose, and being able to take control to work towards your fulfilling desires rather than just choosing the feel-good compulsions forever.
The self-perceived problem with such behavior is not the hours spent per se, but the hours spent in state of absent consciousness. You jump from one compulsory behavior to another, it's not fun, it's just unconscious existence.
