alt Hacker NewsI solve the problem by not throwing things away unless I don't have room for them. As a result, I have electronic components that are 30+ years old.
My wife's strategy on clothes I had that she didn't like was to hide them in the back of the closet. If I hadn't asked where a particular shirt was in a year, that was her signal that it was fine to throw out. Must have worked because I wasn't aware of it until she told me, years later!
I hang my clothes from left to right, so clothes on the left have been worn recently, things on the far right have not. This makes it super simple to once a year, go through the close and just clear out things on the right of every compartment.
