At the heart of this (media or hammer!) is creating limits for you that work! Limiting your stress, overload, work, whatever.
I find getting home, after 8 hours with internet access and no net connectable laptops, I'm frustrated. We don't have a yellowpages anymore - how do I find that ear specialist I read about in the paper? (I went to the library, and the yellowpages don't have an 'ear cleaning' specialists - only auditory services). But by walking to the library, I also did an errand I might not have done, so in that sense it was a win, win, lose (exercise, errand, phonenumber).
I find 'having a life' creates my media fast on weekends. If I make plans, I enjoy those. I don't have a smart phone. I get narky at friends who use their phone (smart or otherwise) with me - do you need to chat to that person/check that fact more than hang out and talk to me? Give me your attention and vice versa? So if I'm out of the house for many hours, or only shortly home, I don't get on the net. Not much happens (emails). Calls are ok, so I suppose it's not a true fast. I suppose I think of a fast in the sense of "laptop closed".
I've taken Oct to be the month without facebook, and I love it! I mean it's not easy to tell 'everyone' about my fracture, or my auction results, but if they are interested, or I can be 'bothered', they'll find out. And the hangers on won't... And by making a call/sending a text, I'm giving one person my full attention in that moment, and that is wonderful for me and them...
