I wish I had some stories as interesting to share as some have posted. I don't, so I'm off going in another direction and naming a few idiosyncrasies I have, and wish I didn't:
1) Have to shower, shave, and be ready to leave home no later than 7 AM, even if I'm going nowhere.
2) I have a list of things I plan to do for the day. I feel insecure if it's not completed.
3) Can never lie down or nap during the day
4) Have to be done for the day by 7 PM. Anything I do after that is me time (no work, etc.)
5) Cannot eat in a restaurant alone
6) Now and then, I take a fun day when I do absolutely no work,  but not unless I allow it in advance.
