I was a collector of shite for many years in the USA then I moved to Thailand where having stuff was pretty untenable because almost nobody had transport larger than a motorbike. I had a new outlook on life and decided that I wasn't going to accumulate stuff. But I ended up accumulating stuff anyway and when I finally had to move somewhere far away again, I realized that I had done it again and most of what I had was stuff that I didn't need. I gave away a ton of stuff and made my whole life fit into 2 suitcases. I have probably managed to get myself up to 3 suitcases since moving to Vietnam but again, most of this is stuff I could easily give away and it seems everyone accumulates such as having far more t-shirts that I will ever wear.
But yes I agree that we don't really need much stuff. Sometimes I am jealous when I see a friend state-side that has a large Lego collection or something like that but mostly I don't really aspire to have those kinds of things anymore.
It's sometimes difficult not to accumulate things, for me too I guess. I look at something and think I paid good money for this and keep it rather than throwing it out...but sometimes a new one is required and I have two. And so the story goes, on and on.
other than the "crap cabinet" that is filled with various wires and other things that look like the might be useful I don't really have a collection of anything anymore. I'm a bit jealous every now and then of people who do collect stuff but a single international move with a dog will quickly convince you to not accumulate things. That has been my experience anyway.
