I am DEFINITELY in the SMing the world category.
I almost obsessively check my cell phone for the time, and each time I calculate what the end of a 10-minute break would be, as well as the 5-minute mark.
I was taking a science class once, where we had weekly quizzes. Each test was timed at 20 minutes. The professor sat in the front and announced, "10 minutes," "5 minutes," "3 minutes," and "1 minute," and it took all of the strength in my body to not respond enthusiastically with "Thank you, 10!" All the strength.
I watch TV or movies--ESPECIALLY movie musicals, and I try to anticipate where cues might be, and thus when they would be called.
My one roommate is INCREDIBLY disorganized. When we leave in the morning for classes, I literally do a 'prop check' of her stuff. Do you have your purse? Your glasses? Your keys? Your tap shoes? Everything.
Also, I am DEFINITELY in the category of organized prompt book, messy everything else. In high school, my parents referred to my room as having a carpet of clothes. My car tends to pile up with empty water/soda bottles, empty fast food bags, textbooks and notebooks, and sometimes even shoes and clothing.
