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 Conjunct Midheaven
Very early in life, you will develop a firm determination to do everything your own way. You decide upon a course of action quite quickly, and you usually know just what you want to accomplish. If someone tries to stop you, you get very angry, feeling that you are the only one who really knows what is right for you and what isn't. Eventually this will be true, but while you are young you should be a little less headstrong and listen to what others say. You won't always follow their advice, but at least give it a hearing. However, you are not merely strong-willed; you also identify yourself very strongly with whatever you intend to do. If someone questions your moves, you take it very personally. You must realize that you are more than the sum of your actions, and that when someone challenges your decisions, that person is not challenging you personally. This aspect indicates that when you are older you should choose a career in which you can have a great deal of independence and expend a lot of physical energy. If you work for someone else, you will frequently feel more like a competitor than an employee, and if you don't like the pace set by your employer, you will feel very angry and hostile. You would not be at your best working in a team situation, with the possible exception of an athletic team. This placement of Mars is very common among athletes; but even in a team sport you need to have opportunities to shine on your own in order to be happy.
