I have always been sort of a Marie Kondo. No more than what I need. BUT because I have in the past thrown away things that I ended up needing, if I do a big purge I put anything I am on the fence about into a box and date it for a year out. Then anything still in the box at the end of its year gets trashed.But then I have to get up the next morning and do it all again!
I'm into Marie Kondo too. The less you have the less there is to wash and put away. Several times I've though about just throwing everything I own away, shaving all the cats and burning the house down. It would save me a lot of time.
