I caught myself about 10yrs ago doing this. I had a business in my 20’s, then liquidated a couple hundred personal firearms with my store inventory when I closed up, but then realized that I had retained and re-accumulated way too many within a few years later. I was building or buying new cartridges to do one thing or another, so I had ONE OR TWO memories on more than a dozen rifles, instead of a dozen memories on one or two rifles. It was pretty hard to liquidate nostalgia, but it was more frustrating to keep so much inventory of rifles from which I just didn’t get much utility. So I did liquidate a bunch, again, and I have multiple rifles with multiple barrels and multiple uppers now - fewer rifles than before.
But I still have a handful of golden oldies I just can’t bring myself to sell, but can’t bring myself to use either.
