Mars is the planet of action, energy, drive, passion, and courage, known for being an aggressor. It is the ruler of Aries and Scorpio, and is exalted in the sign of Capricorn. Now in Cancer, the sign opposite Capricorn, Mars is not in a good placement, and this is considered to be its fall position. It is not that you can not use Mars to your advantage to get things done, however, it is not as likely to be as effective. Cancer energy brings more emotion to the mix, and the emotional nature of things tends to get in the way of the drive to accomplish your goals. Security will be a major focus now, and people will appear to be more easily triggered.
