As I’ve been cleaning out my sewing room and the basement, every little notion or big scrap of fabric or leftover building supply or piece of melamine-covered plywood has to get really CONSIDERED before I decide if I need to keep it or not.
Because the desire to have less stuff and have that stuff organized is directly in opposition to the desire to save something just in case you need that EXACT thing someday.
I’ve seen this happen more than once with my own dad (minus the rolling around on the floor in glee, of course). You never know when you might need that random thing!
