You called planning it "extra" but that's the part I find actually saves time. When I just start pulling clothes out, I get stuck on every single choice. Writing "keep, donate, trash" as columns first means I'm just sorting into pre-made buckets. It turns a big fuzzy job into a simple matching game.
Honestly that planning step just feels like making more work up front to me, @charlesj46. I get stuck way more if I set up all those categories first and start overthinking them. I just have to dive in and make quick choices as I go.
My closet cleanup last month was a total mess, lol. I just started pulling stuff out and got stuck on every choice. Then I tried writing keep, donate, and trash on separate bags. It made everything so much faster, like a matching game. I ended up with three piles in under an hour. That planning step really does save time, no doubt about it.
