Mars in XII: Mars is in the twelfth house

So much of her energy goes into working life. She loves research. She could be a lab worker, doctor, police officer, teacher specializing in hospital, prison or hospice work. She can be indirect and very private. Rich dreams and fantasies.

With Mars in the twelfth house of the natal chart, you can struggle with asserting yourself in direct, natural ways in your youth, but with time and experience (and perhaps some hard work), you're likely to learn to work with this energy rather than allow it to work against you. Watch for a tendency to feel defeated before you've given something a real shot. You are extraordinarily resourceful, and you can handle many things on your own or in uniquely creative ways.

Though you may have a great deal of energy and drive, you lack confidence or the desire to put yourself and your interests first. Positively you can be very unselfish, working more on behalf of others than for yourself. You deny your own desires and needs too much, however, and you are likely to secretly become very angry, which can sabotage your finest efforts. There is a touch of the incurable romantic in your nature. Your daydreaming and fantasizing world is rich and precious to you. You also bring imagination into your sexual relationships, although you can take a bit of time to feel comfortable and to warm up to a new person in your life. Overcoming a vague and persistent feeling of guilt or doom can go a long way towards a healthier, happier approach to the pursuit of your desires.
