This paragraph from Scott Belsky's post at Medium seems key to me.
In a world of twitter, email, endless texts, internet wonder (and now Medium!), create windows of non-stimulation in your day and life - whether through habits or rituals, when you can tune out of everything else and tune into yourself.
It seems more realistic to me to set aside "windows of non-stimulation" when possible or when needed than to insist on a Sabbath shutdown every seven days.
