I had
no idea there was a name for this!! I've been downsizing for months and usually put things in order of 10s (-10 = +1)
I haven't put things in categories though (makeup, skincare, hair products, etc). I think I have little enough (with room
still to use up/get rid of more) that I'll keep with what I'm doing. I will say I feel tons better for doing this. Less guilt with shopping, more space, simplicity, and my skin has actually been better for putting less on it
