For a few years in my 20s I was homeless. Not living on the street, but bouncing around several places back and forth by the grace of friends and (unfortunately) family.
During that time I lived out of about 2 backpacks.
Eventually, I started renting a room in a woman's house, boardinghouse style. This went on for a year.
During that year, I never unpacked. Never accumulated things to decorate my space, or even just to add to the space. Didn't buy any furniture or clothes. Money was tight enough that food was an issue, but even so the real reason I didn't buy anything was the same as when I was homeless.
It was just easier to be able to pack everything into two bags, since I never knew when I'd need to get up and GO. I never wanted to add the friction of inconveniencing someone who might otherwise give me a place to stay by having something bulky - or heaven forbid unnecessary - that I needed to take with me. It was just me, my clothes, and my laptop.
It's been 8 or so years since I've had uncertainty about where I was going to live, and I still find it hard to accumulate stuff. To buy furniture. To buy decorations.
I don't even think about it, it's just instinctive.
I'm only writing about it now because I was cleaning today, the beautiful apartment I share with my partner - and it's full of stuff. Stuff I love, but stuff that will inconvenience us when it's time to move.
And I realized it still makes me anxious. It's still the reason why I hesitate to buy 'stuff'. Even if I don't consciously.
I hope one day I won't be anxious. I hope one day I'll forget I was ever anxious about it at all.
