It's amazing how much things I get done... it literally feels like I have two days instead of one. If I put a item like "outdoor exercise for 30 mins" in my TODO list, then I actually do it! Close friends and family can still reach me by phone/text, but all the chat groups and other messaging app distractions are silent.
I can still end up zoning out watching a movie in the evening, but it's more intentional: I had to pick the movie in advance and download it so I can view it offline.
The contrast with Sunday when I turn the internet back on is very notable. Suddenly the next day is disorganized and end up wasting hours on youtube recommendations, and following rabit holes, and hacker news of course.
My conclusion is that it's not the apps or the internet, it's the feeds (when information is being pushed down to you) that are the problem. It's just too convenient and we end up staying in it.
Highly recommended.
