Great points re the insidious effects of the IT revolution. I spend quite a bit of time online, but I try to ensure that it's either educational (that is, learning about various things that interest me or that are useful to know) or productive (that is, posting on Steemit).
One thing I've done is abandoned my smartphone. Since I spend many hours on my computer, I want to be offline when I leave my home. That gives me time to read magazines or books, or to meet friends.
Before I joined Steemit, I would even go on 10–15 day vacations WITHOUT MY LAPTOP!! That was a great break from all the mails and news and other distractions. I might do that again, on my next vacation.
