I realized just now, at 6:41 a.m. on July 17, 2008, that I have an unhealthy obsession with data in general and the organization of data in particular.
I feel an overwhelming need to put everything in Excel. I think I would die if I didn't have access to it. Well, probably not DIE, but at least have a really big hole in the middle of my entity where Excel belongs.
My budget and bills and many other records are all neatly organized in Excel spreadsheets, each month its own separate sheet within the workbook, columns and rows keeping everything organized, colors and fonts to draw focus where needed, everything in order right down to the last comma and dollar sign.
I created a continuous yearly calendar with a section for notes for the month, each date consisting of two rows and one column, borders and numbering in place. It's easy to copy over to the next year, tweak a couple of formulas, and keep it going to the following year. I fiddled with the fonts and justification to make it aesthetically pleasing, but I didn't use any colors this time. Regardless, it's truly a work of art.
I used to do all of my billing and invoices for my independent contracting business in Word. They were neat and orderly, receiving a face lift now and then with font changes and lines and anything else I could use to make it stand out, distinguish it from the 40,572 other papers sitting on the doctor's desk, so he would remember to pay me. They served me well for more than 10 years, until earlier this year when I just couldn't resist the urge anymore: I was tired of adding lines manually on a calculator billing took forever doing it that way, the more accounts I worked (besides the fact that one of the kids stole my $65 printing calculator left over from my college accounting program days). Why am I torturing myself when Excel will do the work for me!?!? At first, I created billing sheets for each doctor and attached it to the invoice (with a note in the "details" pointing to the Excel data, of course!). Then recently I started sneaking copy-and-paste Excel tables into the invoices, to keep it all on one page and reduce the number of trees I contributed to murdering. Finally, I gave up and generated the entire invoice in Excel. Even that process has morphed recently, each invoice as a separate file now each DOCTOR as a separate "book" with each INVOICE a separate page within. Instead of hundreds of files in dozens of folders and subfolders, I now have 6 files - period.
The depths of my obsession should have become apparent when I made a "camping checklist" (I ranted about my camping stuff before) before my vacation recently so DH wouldn't forget things, said list proceeding immediately from his fingertips into the trashcan. "I know how to pack, I'm not stupid." Columns dividing gear, clothing, food, etc.
In retrospect, I can see that this isn't a new issue like my memory problems, something I can readily attribute to cognitive or psychiatric consequences of MS. In cleaning up my computer files - the time during which I decided to streamline the doc's accounting processes - I notice that I've been sneaking Excel worksheets into my life for years.
When You-Know-Who started bitching and moaning that I wasn't sending "her" money to her and filed a contempt motion against us for violation of the custody orders, I started a log: Each month I cut her a check for 1/2 of the girls' Social Security benefits received and recorded the date, amount, check number, and any amount she indicated to me (in writing!!!) to deduct, like 1/2 of their school lunch costs. After she cashed each check, I entered the date cleared by my bank.
Some dickweed keeps leaving my DVDs lying around, since putting them away when they're finished with them would be too easy, and many are lost, broken, or deeply scratched; another dickweed borrows them without asking then sells them on eBay. I have a list of all of the DVDs I've bought, separated into genre, with a column for those that are missing. (This was part of a document for my house insurance listing everything I owned, something about it being a cost of replacement policy.)
I didn't have the time or inclination to go buy real blueprint paper, so I made a grid to "blueprint" my staircases, each square representing 1 inch.
With the second FT job I worked a while back, I kept a workbook with each pay period - you guessed it - on a separate sheet with days, times in/out, and lines transcribed. We didn't have a "time clock" to punch, but we had to enter all of that into the time card at the end of the pay period. My time sheet book had formulas to calculate daily hours worked, lines per hour, downtime, and gross earnings. I have another that I made for my current job, when they wanted me to start documenting what I was doing each and every minute of my 8-hour shift every day (a story for another day).
I haven't gotten a notice yet on my 2008-2009 federal student loan interest rate and monthly payment amounts, but I have a spreadsheet to enter them into when I do, tracking the 10-year trend of this information, complete with the change in each from year to year since I went into repayment.

When I was working 2 full-time jobs and 1 part-time job, classically "employed" at 3 different companies, AND self-employed as an independent contractor for between 3 and 6 doctors across 4 different accounts, I made a schedule to plan my time, columns Monday through Sunday, time in 24 rows of 1-hour blocks, midnight to midnight. Each job was color coded, so I knew what I should be doing at any given time, when I could schedule a doctor's appointment and even when I could sleep.

The fuse box in our house had something not quite right going on with it. Although my office had been split across 2 breakers and the kitchen had been split across an additional 2 breakers (high usage areas, to prevent tripping the breaker), every time someone would turn on the microwave in the kitchen at the other end of the house, the whole kitchen and one side of my office would blow. We needed to map out the fuse box to see which breakers controlled each area of the house, since things got kind of buggered during the remodeling, so I made a chart.
There are no depths to which I will not stoop in order to create an Excel worksheet for
something, but I can't organize my desk to save my life. Whenever I need an ink pen, I have to sift through a mountain of papers, which curiously are often hard copies documenting my passion for data organization, even though I have filing cabinets. Filing doesn't involve using Excel, so it doesn't interest me.
