I've always said that I'd make a good accountant/bookkeeper, and I still sometimes debate going into that field. Case in point:
I just spent an hour reconciling my monthly reports with my ongoing tally in my 101 things in 1001 days challenge. Turns out I had missed 2 goals in my monthly tally on month 3. I had made separate blog posts for each of those, so they had gotten crossed off on my master list, but they weren't included in the running tally I keep for each month of progress.
When I reported this time expenditure to my boyfriend, he laughed at me and explained his humor thusly: "you just couldn't let it be, could you?"
Nope, I just can't. I've always figured numbers in two different ways, and I need to have those two lists reconciled. I've known about the mishap for a few days now, but today was my first day where I got a long enough break to actually fix it all (I should admit that I have looked over my lists and casually tried to find the issue on other days, but I could only devote a few minutes before today).
I feel much better now.
