Sagittarius (November 22 to December 21)

Pack your bags.

You are a fire sign, which means you're a mover. "You're very much focused on truth and philosophy and worldly pursuits," says Rogers. As a wanderer, if you don't have your freedom, or feel like you're boxed in in some way that prevents you from stepping outside of your comfort zone, you're apt to get cranky. Bust stress by pursuing activities that put you in a different, foreign-to-you space. Book a trip (anticipation of a vacation can be one big mood booster), sign up to learn a new language or stay in your neighborhood and try a new cuisine.
