I maincally run around my apartment making sure no faucets/toilet are running; make sure all lights and electrical appliances/gadgets are turned off; make sure I have my mobile, keys, and wallet; when I lock my door I always shake it vigorously to make sure it is locked [as a result I fear I shall shake it to disrepair (my father has yelled at me about my intense door-shaking)]; on my way out to my car there is this bar and I invariably do 10 pull-ups on it-- I have no idea why anymore, maybe to facillitate a bit of endorphine release and psyche myself up for a day of monotony/nervous attacks. As I am pulling out of my driveway I sometimes have to get out and rush back to make sure my toilet is not running. Truly bad days seem to coincide with this desire, so it is a wonder I just don't even bother going out when I experience this impulsion. One must placate bosses, professors, and the gods, of course, so I usually just fortify my resolve and prepare for a crap day.
