That "museum of might need it someday" hit me hard... I've got a drawer full of weird cables that look like they're from a spaceship. The thing is half of those old cords and switches aren't even for stuff we own anymore. They just sit there like proof we tried to fix something once, and throwing them out feels like admitting we never will.
Actually, those spare cables can be real lifesavers when you least expect it. I've loaned out odd connectors to friends more times than I can count, and @wendy674's garage stash might just help someone too. It's about being resourceful, not hoarding pointless things.
