I found out I did the exact same thing when I deleted my Reddit account and set limits here on HN. I used to find myself unlocking my phone, looking at it, opening Google News to the same old articles, then locking it and doing something else. I have gotten much more stuff done now that I don't stare at Reddit/HN/other all day.
I feel like society should try to back away from being slaves to our technology, and maybe the popping of the social media bubble, via people realizing how much data they collect, may be the trick to do this.
