I read the article linked above. No specific instructions given.
Really, I think the trick is to just put in the time. We don't like spending time on papers, seems so unproductive. But spend an hour looking for a paper or a piece of information and that might change your mind.
My plastic folder holder I keep in the kitchen to corral all the stuff all over the kitchen table does not offer any benefit except for a neat place to keep all the mess. That's the way DH keeps his stuff and I am the only one who stuffs papers in the folders. I think we've only gone diving in there once or twice in all this time looking for something.
Can't imagine having the papers like Lucylee has. DH empties his pockets on the kitchen island, receipts all balled up, papers, etc. and if I don't keep them moved they get wet from overspray from the kitchen faucet which is also in that island. The mess annoys me and feels stressful.
To put my paperwork in perspective, in 2018 I wrote out $340,302.00+ of checks just for the business. Receipts galore, which I copy to put in job folders ready for billing, etc. Most of those checks were less than $100, some less than $20. Only a few were a thousand $. Which does not even include the work of billing, banking, statements, permit and plan work (huge job) and payroll and tax work.
And all I can think about is sitting down to work my newest jigsaw puzzle! DD bought me a beautiful flower shop one that we've decided would be nice glued together and framed for spring & summer.
But first I have to finish getting my tax stuff together and the rest of my stuff for my insurance audit which should happen next month.
Someone somewhere surely has a good system for paperwork. I will do a search.. Ok I did search around and I find cutesy little gadgets for organizing one's paperwork, baskets for caroling recyclables, stuff like that. And tips for dealing with mail, catalogs, magazines, receipts. I think your system should be your own, because we all have different needs and use things differently. It comes back down to putting in the time. And keeping it up. Not helpful, I know, but that's all I got.
