Exercise in self-exploration (suitable for grades 7-college):
Write down all your guilty pleasures. Then read them and realize how weird you really are.

Example for the class:

My guilty pleasures include…
~Having 7+ items on my taskbar at once and going through them (while knowing what each one is and at what point in time I am in for each activity), chuckling with glee as I bask in the awesomeness of my ability to multitask.
~Analyzing my dreams, Freudian style!
~Planning. Everything. Down to the second.
~Being spontaneous. Then realizing that I’d planned whatever it was all along. All of it. Down to the second.
~Surfing around on eBay (I do this way too much)
~On MySpace, going to all my friends’ friends’ pages, then branching off from theirs, and on and on until I reach people in Uzbekistan (true story) in my never-ending quest to find interesting blogs to read.
~Tests and Measurements.
~Fantasizing about everything and anything. I spend a lot of time up in my head, if you don’t already know.
~Reading fan fiction.
~Listening to “O Magnum Mysterium” on full volume in my dorm room with the lights off. It is now a nightly ritual.
~Pretending I’m cool.
~Pretending I’m funny.
~Pretending other people think I’m cool and funny.
