All great points. Too many people are afraid to disconnect for fear of missing something “important” while they ignore what’s most important to their own lives.
Personally, I got over this through a series of small and expanding experiments with turning off notifications and also using the Do Not Disturb feature. I prefer DND over Airplane Mode so that I can connect to things as I want, without being disturbed by the incoming pings.
It’s a process of training yourself not to go to the apps that will suck you in (email, Facebook, etc). I recently took a 3-week break from email without an autoresponder. Nobody died. Clients who needed me found me a different way. It’s all possible. :-)
