Everyone has a junk drawer full of random, mysterious stuff. The occasional battery, old hair ties, bits of string, matchboxes — you name it, it's in there. And it just gathers drawer dust. So try this little experiment for a month. Grab a box and empty the contents of the junk drawer into it. Then, if you use something from that box, put it back in the junk drawer. At the end of one month, the drawer will be filled with items you use. The box? That's all stuff you can donate or throw out.
