I know that I sometimes struggle with pulling my phone out for no reason and refreshing HN or Reddit. Same with my laptop during work hours. I don't like it and I'm trying to do better; I want a healthier relationship with my devices and the internet.
I definitely took something from this article, though. For a while I've been using Do Not Disturb to cut down on distracting notifications throughout the day, with a whitelist for family members in case of emergency. But from now on, my phone's WiFi will be turned off and I've also disabled cellular data for all other non-critical applications.
Now if I want to refresh HN or Reddit for no reason, I either have to connect to WiFi or explicitly grant Safari permission to use cellular data. Overall, I feel like I'm taking steps in the right direction...
