So here's the thing about the 90-90 rule – it's dead simple. Like, almost stupidly simple. Two questions. That's it. Popularized by Joshua Fields Millburn from The Minimalists, it helps you finally decide what stays and what goes. You just ask yourself: "Have I touched this thing in the last three months?" and "Do I actually see myself using it in the next three months?" If you're answering no twice, buddy, it's time to say goodbye. You pick something up. Any old thing. Then you ask those two questions. The first one's about the past – did this get any use? The second is about the future – will it? And that's where the magic happens. Because suddenly all that "well maybe someday" crap disappears. Like that weird kitchen gadget you bought on impulse. Haven't touched it in months. Can't picture using it anytime soon. Out it goes. Simple as that. Look, no rule's perfect. Not even this one. There are obvious exceptions. Your winter coat? Your holiday decorations? Those need a full year, not 90 days. Sentimental stuff – grandma's china, old photos – that's a whole different ballgame. And emergency stuff? First aid kits, fire extinguishers? You keep those because you might need them someday, not because you use them daily. The rule's a guide, not a straightjacket. Use your brain. Hell yes. It's actually perfect for that. Think about all those apps on your phone you never open. Files on your computer you forgot existed. Emails dating back to 2017. If you haven't opened it in 90 days and can't see why you would in the next 90? Delete. Archive. Gone. Keeps your digital life clean. Maybe? It can be a useful tool because it's so objective. Takes the emotion out. That "what if I need this" anxiety? The 90-day limit gives you a firm answer. But honestly, if it's serious hoarding? You need professional help. A therapist, an organizer. The rule alone won't fix deeper issues. C'mon. Don't be that person. The rule's a guideline, not a law. If you used it 89 days ago, you're probably using it regularly. The point is to catch stuff you've truly abandoned. If you're genuinely unsure, keep it for another cycle. Be honest with yourself about your actual habits. If you've got a wedding, a trip, a party planned in the next 90 days? Keep it. The "next 90 days" question is about specific, planned stuff, not vague possibilities. If the event's further out, maybe stash it somewhere else and revisit it when things get closer. Don't let the rule make you toss something you'll genuinely need soon. Here's how to actually do this thing. Step by step. Joshua Fields Millburn from The Minimalists made it popular. It's a big part of their whole decluttering thing – shows up in their books and podcasts. Nope. Anyone can use it. It's just a practical tool. You don't have to be some extreme minimalist to find it useful. Absolutely. Those spaces are perfect for it. Half the stuff in there probably hasn't been touched in years. The 90-day filter will separate the necessities from the forgotten junk real quick. The 90-90 rule's not for that. Use something else – KonMari, maybe. Or just keep a small "memory box" for the stuff that really matters.What is the 90-90 rule for decluttering
