I've recently been trying to reduce my possession footprint. It partially started in 2015 with the move, but it was more a utilitarian process of "will or won't I need this?" than a introspective "why do I have this and what do I still think about it?" It's good to do that time-to-time to remove the glut of stupid possessions that we all pile up. I like to reflect on what I own, with the Fight Club quote "The things you own, end up owning you" still hanging on after all these years.
