Mars traveling through your opposite sign of Sagittarius (November 20th to January 4th) isn't easy. Confrontational and combative, this planet's adversarial energy will pressure you into relinquishing a prize, claim, or title. At first, you'll want to defend what's yours, but this might be a good time to put on your Gemini thinking cap. What is the other party offering to make this worth your while? There's a lot to be said for having something that somebody else wants, and if this person is desperate enough – which remains to be seen – you could wind up walking away with something better than what's already in hand.
