One of my favorite parts about living in constraints is it forces me to build new mental models.
I wish I could say we have kept this up now we are back living in the "real world" but some of the spirit has rubbed off and we're definitely much better at becoming less attached to particular belongings.
I strongly believe that most belongings end up becoming burdens if you don't establish a process of questioning their utility on a somewhat regular basis.
Thanks for the article! Really thought-provoking.
