This time of year is always tough for me (like many many midwesterners I have SAD) and I tend to turn inward. It's scary but can also be very very productive. During this introspection I generally beat myself up about stupid stuff, but occasionally I just let my mind wander and I have a little breakthrough. Like, I just discovered a brand new turn-on that I never new about. (This is where I almost said what it is, but I don't want to have to explain the intricacies of it.)
ANYWAY, go forth and discover yourselves!
