Lack of foresight

Going through my things is just as agonizing as you would imagine, but it does come with its perks. I’ve sent three bags of clothes to goodwill, cleaned out my bookcase, and decided what to do with some gadgets. The problem is when you get to the small stuff, the clutter in the drawers. On the one hand, if I didn’t remember a thing existed, why keep it? But on the other, hey, I got it for a reason in the first place. The does this make me happy? method doesn’t apply to everything, because if I’ll need an item in the future, it sure won’t make me happy having to buy it again just because I trashed it due to lack of foresight.
