So I am sitting here at 6 Am on a Saturday morning going through paperwork. Handling paper tends to be difficult ofr ADHD-ers. IN my Household, 2 of us have been diagnosed and treated for ADHD. Most people think I "Outgrew" it, but I say I just learned good coping techniques.
So when paper comes in, I have a "bill basket" it is actually a box that some bath gel came in. I found this time that I left this a bit longer than usual and the box was full and I had another basekt (Longaberger Spring) that was about half full. So I sat down, opened the envelopes and immediaely started 2 piles, trash and shred. I also have a simple box folder filled with several file folders. They are labeled: Tax, Medical/Dental, Assets, School Insurance and "credit crap". Every few months I sit down and go through all of my statements. I shred what needs to be shredded, throw away the trash (envelopes, other pamphlets without personal information). I also find I have put reciepts for thing like Prescritions that I used the flexible benefits debit card for. This way if I need to go back and find something, I can go throguh one file folder thinking "I know I saw that somewhere."
My file cabinet is more divided, but I tend to file stuff away in it once a year, usually when I run through taxes. The two step file method works well with my personality. Just remeber to keep it simple.
