Have you ever met anyone who is the polar opposite of a hoarder? Like someone who cannot tolerate owning stuff and frequently throws out or sells stuff they need which they later need to buy again.
Three piles. Background, I moved roughly every two years from 1 until mid twenties. Not a military family. Even with this I still move several boxes of stuff that I never open until the next move.
First pile is stuff you must keep/love.
Second is stuff that is okay or may be nice-to-have.
Third is stuff that can be sold/donated/disposed of.
