Mars represents our ambition, energy, action and desire. It rules our basic instincts of aggression, anger and survival. There is often no contemplation before action when it comes to this primal energy. All our sexual desires come under Mars. This is the raw physical energy as opposed to the creative energy of the sun. With good Mars placement we are assertive, directed and forthright with bad placement we an be impulsive,rash and aggressive. In your chart, Mars shows your basic animal nature, how you express anger and what gets you angry and more importantly what makes you act.
Mars Trine Midheaven
You have a strong sense of self - that is, you know who you are and what your rights are with regard to other people. You have considerable self-confidence and will fight for what you believe to be yours. On the other hand, you are less likely to dominate people than those with other Mars-Midheaven combinations. You do have a great deal of physical energy, however, especially in activities that you want to be involved in. As you get older, you will pour out energy in your work and career, and you will be known as a very hard worker. But you may not feel that you are working hard, because the energy comes so spontaneously that you do not regard it as work. For this reason, you should look for a task or purpose that your life can revolve around, that you can identify closely with. While you are young, this may simply be a hobby, but later on it will be your career or life work. Fortunately, with this aspect you won't have much trouble finding a purpose in life. You are not especially competitive, but you are independent. You do not like to be dependent on other people; nor do you like anyone to interfere with the schedule you have set for yourself. Consequently, you may find it easier to work and play alone than with others. When you have to make a choice, you are usually able to do so quickly and easily, because you know pretty much what you want, and you go after it. If you don't know which of two choices to take, you may make an arbitrary decision, feeling that making some choice is better than going nowhere.
It is a time where you will be very confident and self assured. You have the resources to accomplish any objectives you have in your mind. You have the ability to work hard and work with others to achieve success. You can and will take risks and it is most likely that everything should turn out well. It would be good to exercise if you find your energy is at a very high level.
