I'm almost assured in my belief that life without all this technology wouldn't be easier, but it'd at least be quieter. I think about it a lot. I think I could do it.
Do a little experiment. Calm down for 10 seconds and try to think of as little as possible. Now imagine you get an email, a message on Facebook or any other notification. How does that make you feel? If you're like me a few month ago, it might stress you out and you might feel an urge to read it. That's when I turned off nearly all (regular calls ring normally) notifications. It's not an abstinence from technology, but it is indeed a quieter life. Checking everything when it's a good time for me instead of constantly being ripped from my current train of thought by notifications makes all the difference to me.
