Organization is a key skill for going "not new"...unfortunately, I'm lacking.

Haven't had to buy much lately. (I did purchase a gift...my first I'll be giving that's "not new," but I haven't given it yet, so info will have to wait for another post.) I did decide to keep the $25 Chefman blender as I've been to several other sales and thirft stores and haven't found what I wanted, plus, I happened to wander into Ollie's again and they don't have any more available, so that sealed the deal.
My problem now is trying to organize stuff I feel I should keep on hand. For instance, I have a broken phone charger for my car. The wire on that thing could make a handy tie for a plant...it is strong, yet the rubber coating would protect the plant. But, how am I going to keep things from getting crazy if I start holding onto stupid little things like that? Sigh. I saved it because I felt I had a good place for it, but I am worried about becoming a pack rat (I already have those tendencies).
