I’ve been 24/7 do-not-disturb mode with all notifications disabled, for the past 10 years. It’s been wonderful for “intentionality” and agency over my time. I use my phone when I want to do something on it, not when the phone beeps and buzzes telling me to use it.
I don’t even whitelist anyone anymore. If it’s important they will leave a message and I’ll get back to them.

I can't really do that. For some things (urgent and important), loved ones need to be able to reach me.
But yes, a lot of this advice would work.
