The Midheaven is the point at which the ecliptic meets the meridian at the moment of birth. Put quite simply: at the top of the sky at the moment and place of birth.
The MC tells us what you identify with in life. The characteristics of the sign on the MC will be important to you - they will be recognized and admired and you will consciously or unconsciously aim to express them. They are not necessarily part of the sign on the Midheaven: A Capricornian MC does not give you the characteristics of a Capricorn but you would identify with the qualities that are most important to Capricorns.
Midheaven in Aries
You surge toward new careers many times in life, with some false starts abandoned. This gives you an edge in the current atmosphere (with the need to change careers), and a willingness to forge ahead in new areas. A need to be boss opens the door for self-employment. You are the dynamic leader, whether on stage, in the military, in sports, business, law, politics. A naturally competitive (and combative) public persona brings you success in a fighting role in whatever field you choose. You're not afraid to take daring risks, and that sets you apart. You like to be a trailblazer, and can be a model in these times for great leaps into the evolutionary future.

A very creative Mid-heaven, that sets you up to be an artist, performer, a healer, a friend to kids and animals, and use your intuition as a tool. Your strength is your sensitivity, but also may keep you from claiming your full potential. Your gift is to shape the collective messages, through song, story, nurturing, spiritual teachings, and just by being who you are. You may be drawn to working on or near the water, and have the ability to tune into non-verbal kinds of communication (animals, marine life, nature spirits, elementals, inter-dimensional beings). Pisces rules the feet, and this could lead to work as a reflexologist, podiatrist or just someone that loves to give/receive foot massages!
