I've noticed myself already falling into trends and doing weird ritualistic activities only three weeks after I've arrived here. Some of them are kind of amusing, so I thought I'd share.
Get a caramel iced late from Jazzman's every morning. - It's not that I get the coffee because I'm tired (even though most mornings I'm exhausted), it's just that it tastes good and it's on my way between classes. Jazzman's is sorta just sitting there taunting me as I walk from Smith to Albertus-Magnus, and I just have to get my morning dessert. And this is why my PC bucks are dying so fast.
If I'm lucky, get 7 hours of sleep a night. - I used to get at least 9 hours of sleep every night. Now I find myself hardly ever tired except for random spouts during the day, and a healthy dosage of adrenaline and coffee can fix this. But at night as I lay down, I just can't sleep until like 1 in the morning. And then I wake up at 7.
Go to lunch and dinner pretty much at the same time every day. - My schedule pretty much dictates when I can eat, as I only have a single hour break on Mondays, Wednesdays, and Thursdays. Because of this I eat with pretty much the same people at the same time every day.
Be late for my help desk shift pretty much every morning. - I've actually had to start setting my alarm clock earlier and earlier, as there's just something about the lovely snooze button that makes me want to press it 500 times before I finally get up. And then I'm pretty much always late. At least my boss is awesome.
Send at least 20 text messages a day. - I've never been much of a cell phone/texter before I came here, but for some reason it's like the text messaging beast emerged the moment I arrived. It's kind of a problem and I'm willing to admit that I need help.
Organize the random outings my group of friends and I go on. - I don't know when this happened, but it's like I've sort of been put in charge as the person who organizes all the random happenings we embark on. I call everyone twice, say when we're gonna meet and find out if they can go, and use up my minutes all the faster. It's a grand time.

Sing solfege pretty much whenever I'm alone for more then 5 seconds. - This is kind of a music major thing, but it's certainly new. There's always solfege, or do re mi fa so la ti do, going on my head. I challenge myself and try to sing different harmonics almost all the time. I'm pretty sure it's unhealthy.
Forget my dirty laundry in the washer and dryer room, mid-wash. - This is just because my mind's always all over the place, but it's a problem nonetheless. I'll put my laundry in, then on several occasions just go out and forget about it for hours. I'll come back to find it either on top of the dryers or tossed all over the floor. I suppose I get what's coming to me.
Lock myself out of my room at least 3 times a week. - I seriously hate the St. Joe's dorm doors. I just want a combination to press in rather then this annoying swiping system, because if I lock my card in I'm pretty much doomed. And being the absent-minded kinda person I am, this happens a lot.
Drop all my books on my bed and just leave them there to "clean up later." - This is what makes my dorm a typical guy's dorm. The mess is just as grand as you'd imagine it would be.
I'm sort of curious if I'll be doing these things at the end of the semester. I'll get back to you about that.
