You knew this was coming: Exercise boosts those all-important serotonin levels that help regulate mood and mental health, so it's pretty crucial to combatting S.A.D. If I feel inclined to binge a show, I make myself a deal that I have to watch at least two episodes on the Stairmaster or elliptical, then I can watch the rest at home.

As a writer, I can make any excuse to spend weeks without leaving my house if I'm on a deadline, which means it can be a long, depressing time in solitude if I don't watch it.

There is no better time to skip town than when it's dark, cold, and lonely where you are. There are plenty of airline deals after the New Year, and there are countless tickets to destinations for next to nothing. If you're so poor you can barely pay attention, drive or take transit to visit a nearby beach or town. Last winter, I took the subway to various places I'd never seen before.

As an introvert, I should throw this in here: I am positively drained by long-term contact with lots of people. I have to be alone for a while just to feel normal again.
