Getting Things Done’s “In-Tray” but for real life items.
As for take-off points, I use the doorway of every room I’m currently in… seems counterintuitive, but by dumping things in a doorway, you’re deliberately making it annoying to leave the room, so when you do need to leave the room, pick it up and either pack it away right now or dump it in /that/ room’s In-Tray.
So each room effectively has an In-Tray and an Out-Tray, but instead of yet another physical item you need to buy or at least take up space, the doorway will always be there!
You underestimate my brain's super human ability to justify leaving that stuff right where it is until "later" which actually means never but for some reason I accept it lol. Oddly enough, this only applies to things that I personally leave in stupid places.
If I work on my PC or server hardware at the dining room table I will end up with random components/tools/hardware left there after I finish and my brain will tell me "This is fine, we have something else to do right this second!"
If one of my kids leaves something like a bag of chips on the table right next to that pile of stuff I left behind, my brain will blow a gasket and make having the remediation of the chip bags misplacement by the offender as the super most toppest priority to address right this very second.
So under your system I'd end up with all my stuff in my house's doorways and 2 annoyed teenagers who will probably extract revenge by "cleaning up" my doorways and since they are teenagers and share DNA with me, not a single one of those items will find it's way to it's proper place! ADHD is an adventure for sure lol.
The sequel Making It All Work mentions a tidying strategy of first putting everything that's out of place into a big "bucket" (e.g. laundry hamper), then dealing with them one by one.
