You know what makes me happy? That I've been asked to do some research on circadian rhythms. I pulled up PubMed and found more than enough citations to fill the 8-10 hours I have to do the review in. (That's total hours, by the way, not consecutive, immediate hours.) I think I'm happiest when I get to look at science-type stuff for short periods of time--when no one expects me to be an expert at the subject, just to learn enough to tell other people. Now what kind of job would that suit? At any rate, it suits my own for a few hours, and that pleases me.
