My default position towards things is hate. I hate stuff. It gets dusty, it has to be managed, it takes up space. A room with lots of stuff in it is cognitively difficult for the brain to process; having lots of stuff around actually drains your mental energy.

I generally dislike owning things that I can't physically carry with me at all times (because "if you don't have something with you, owning it probably hasn't made you more powerful"). Consequently, the majority of what I own I carry with me. The only real exceptions are clothes and books, and I launched a project this week to replace the latter with digital versions which is moving at a decent rate of ten shelves a day.
