I think this habit developed from over 20 years in the Air Force ...but we always "purge" our home every six months. While in the military they will only ship a certain amount and pay for it. Anything over that alloted amount we had to pay for so like most military folks we kept our household goods under that set weight. Now it is a habit - if we have not used it in 6 months we probably don't need it and we purge it by giving it away, selling it or donating it. Sure keeps the house neat and I have never found (yet) that I got rid I something I went looking for at a later time.
