This is exactly my problem. It's easy enough to say "give it away if you won't use it soon" but how do you know ? That urge might come on any time, and the act of giving it away is likely to reignite that passion. And for small things, like cables you don't often use... You never know when you'll need them. I've been telling myself I'm just going to throw them away after all, but then within a month of deciding that,…
Pick a dollar amount and delivery time period you are comfortable with. Get rid of everything you haven’t used in a month that you can get cheaper than that amount and within that time period. Dont justify after the fact just dumbly implement the rule.
Keep a few extra cables of sorts I actually use fairly often (a few spare HDMI cables, some ethernet cables, and a few types of USB cables are no-brainers, for instance). Toss all the rest (am I ever, ever going to use a DVI cable again in my life? Decent odds, no, and on the off chance I do I can just buy another)
Any cable that's more than ~2 spares for a port on some device that is plugged in or otherwise in-use in your house, or isn't a kind of port you've used in a couple years (even if you could) should at least get some serious scrutiny and more often than not be donated or go in the trash.
Like, I held on to a couple coax cables more than ten years after the last time I plugged anything into a coax jack. So stupid, in hindsight.
