I pack what I depend upon, but only work 3 days a week at the office. Among my everyday items:
1L nalgene bottle (fill it when I get in in the AM)
FAK with various small supplies (nothing for trauma, but I do keep that in my jeep)
SAK (Hiker model)
small flashlight

I also carry on me me Leatherman, a folder pocketknife, a DR picolight, a p38, and some 550 cord (about 10').

I also take a week's worth of lunch in & keep it in my drawer-granola bars, dried fruit, crackers, tuna fish, soup, etc-varies week to week. There is enough to get by on for a couple days, should, for some odd reason, I get stuck here.

MY clothing is ALWAYS utilitarian. I wear cargo pants, or dress pants that have hidden cargo pockets, comfortable shirts, always have a jacket & hat, and comfortable shoes to walk in.
