What is the 90/90 rule for decluttering?
Two questions about one item: have you used it in the last 90 days, and will you use it in the next 90? If the answer to both is no, it can go.
It works because it replaces a hard question with an easy one. "Do I need this?" invites a story about who you might be someday. "Have I touched it since spring?" has an answer.
Use it on the things that stall you: the small appliance, the jacket, the third set of measuring cups. Keep the seasonal exceptions out of it. Ski gear in July is not clutter, it is just July.
