That’s a great list.
I’d have to agree this is better for overall stress levels.
The first two and last I’ve followed pretty well, only follow a few topics I care about but turned off all notifications to avoid being pulled in.
The phone is surprising though. I would say it’s nearly impossible to let go although recently I’ve been forced to because of an issue porting a number. So for a week now only a few actual work calls come my way and it makes a huge difference. It still feels weird and unfortunately I’m sure some work related items are being missed because of people having access to me on multiple numbers.
