And yes to your PPPS. My plan is to live out my favorite childhood book The Alchemist in New Zealand while retracing the LOTR filming sites with a herd of sheep and a shepherds crook. One of the sheep will be fitted with solar panels and Starlink though, cause I just gotta have my Love After Lockup.
Edit: and to be clear it doesn’t have to be an all or nothing thing. You can reenable notifications on a per app basis (and on Android per notification type I believe). You can turn them on for an app for a few days to see how intrusive their notifications are. Just make it a habit to turn them off at the drop of a hat with extreme prejudice. If you need stuff for work make rules and automations to turn stuff on and off based on triggers.
