Mars Square Ascendant
Your psychological drive towards acting on the basis of your conscious feel-
ings about people and situations is strongly developed, but it operates in a
way which goes against your spontaneous, more natural approach to life,
resulting in your giving out double messages. You are likely to experience
a conflict of interests between fulfilling your own needs and getting along
with other people. You either feel you must have your own way at all costs,
which will lead to disputes with others, or you feel you must get along with
people and therefore suppress your own wishes. In either case anger is a
feeling you have to learn to express appropriately, neither going overboard,
nor allowing people to walk all over you while you feel frustrated.
