My boundaries all revolved around my smartphone. By simply putting my phone on the kitchen counter as soon as I walked in the door and not having it on my person for the rest of the evening, I had eliminated the compulsion (and the ability) to check my email and feed that any-benefit-driven monster I so desperately wanted to avoid.

Sounds like a perfect strategy. Turns out the hardest habit to break is going back to said place you left your phone and pick it up again – who knew.
