If your Mars is in Capricorn
You play the long game. A five-year plan doesn't scare you, and you'll still be putting in the hours when the novelty is long gone. Your anger shows in a cool, clipped tone more often than in a raised voice. What can get lost is play, when everything starts to look like a job. You're allowed to want something just because you want it.
Don't know your Mars sign? In most cases, your birth date is all you need to look it up.
