I heard it on the radio, so I don't know if it'll work but it's worth a try.
Apparently, the best way to clean out your kitchen stuff is a drawer at a time.
Put all the items of the drawer in a basket , and the items you don't use over the week you discard to the cellar, lol.
The bedroom sounds challenging. For every 3 items you toss 1 item.
I suppose I could do this but it does seem a waste. I better make sure I donate to St Vincent De Paul.
