I really like the insight about density. I temporarily changed my living situation from a 4 bedroom house where my kids had moved out, to a 2 br apartment and I recognized the density issue but had not conceptualized it so clearly as the author did.
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.
