T.B.
It has to be "yours" - no one else's will work. I'm addicted to Real Simple and they can't give me a system I like. Start by writing down how you think. For me, I need to file "current paperwork", "annual paperwork", "recipes", "kids ideas", etc.
Current Paperwork turned into the top drawer of my filing cabinet with things like a file for each item like "cash receipts", "Visa", "401k", "Health insurance" and I file things that are monthly in there. I heard about making your inbox with a lid so that if you can't close it, you must file. I'm doing better, but looking to get one of those soon! I try to file as the papers come in or at least once a week.
The "Annual Paperwork" are files I access once a year, go in the bottom drawer, and those are things I need for reference (i.e. insurance papers, manuals for big ticket items, gift receipts, tax returns.
Recipes I used the other mom's idea - 3 ring binders. If I try a recipe and get one negative response at dinner, it gets tossed. Currently, I have 2 big binders and 1 for "kids" recipes.
The other ideas (mostly newspaper and magazine clippings) are in binders that I used about 2 days' worth of naptime to organize. All are in 3 rings and I used dividers. I'm very thrify, but splurged on good binders ($10 each?) as I know I'll access them over the years.
I'm not perfect, but that works for me!
