I mean to say, it's difficult stopping as long as they keep producing them. If I have one of them, I must have all of them, even if I don't want them. It's the completionist in me. We have two sets of plastic Hallmark ornaments that we haven't used since 2003 or so...they're still making them, so we're still buying them, and tossing them right into the storage bin. I've also been slowly filling in the missing Swarovski ones as I can find them online.If stopping is a problem, why don't you just change to something else?
It's the same reason, if I watch an episode of a TV show, I have to watch all the episodes, even if I hate the series (I'm looking at you, Black Mirror...and Hemlock Grove...and a dozen others).
