One thing that I've done to combat the invasiveness of modern technology is creating a home computer station and removing the more troubling apps off my phone. I have a laptop that doesn't have a battery pack so it has essentially become my desktop PC. By making it inconvenient to access things like FB and Instagram, it makes it less likely that I will throughout the week.
It's not a perfect fix, but it keeps me from doomscrolling all day. I still have the Little Internet in my pocket, but now I use it to find customer answers while I'm at work instead of being locked in and constantly craving the low level dopamine of the algorithm. I'm certainly not completely free, and I can't quite make the move to a dumb phone yet, but this is a small move that works for me.
What are some of the things you've done in your life that lets you start breaking away? I'd love to hear them!
