Holding on to things you don't use isn't thrifty

I keep a donation box in my closet. For most things, the rule is: “if you bring something in to the house, you put something into the box.” I periodically give away the stuff in the box. This was really hard to do when I had the “this may come in handy some day” mentality, but I have got over that by telling myself “somebody probably has a use for this right now.”  It is SO much easier to stay organized and find the things we do make use of when there aren't a lot of other things in the way.
