If you depend on Facebook for managing a page (work, band, etc), just use the dedicated Pages application. Same applies for Messenger if you don't want to get rid of it.
It's helped me curb the ridiculous "CTRL+T, fa, enter" reflex - seeing the login page instead of my Facebook feed every time I do this makes me notice how out of hand this has gotten for me.
I am so sorry I ever joined that f*cking site.
In general I have tried to remove myself from things that keep my attention on my phone rather than what's going on around me. Now I sort of get frustrated when people ask me what they missed or what just happened in the real world while they were glancing down.
I have friends and family who I think have completely forgotten what's it like to just be a passenger in a car watching the world go by, because if they're not driving they're looking at Facebook or Instagram.
What made the original Facebook hateful when compared with other "hot-or-not" sites?
