Mercury represents our rational mind and is the planet of everyday expression and communication. It signifies our curiosity and what areas of life we find mentally appealing and stimulating. It analyzes and organises and defines the way we interact with others. Mercury in your chart reveals how you get your point across and in what style.
Mercury Conjunct Midheaven
This aspect means that you have a very sharp mind, which you will use to get ahead. Very early in your life, you will learn to look at the world clearly and objectively, and you will learn to communicate in ways that are very advanced for your age. You may or may not become an intellectual when you are older, but you will use your mind continually, always searching for stimulating and exciting experiences. Because you cannot stand boredom, you are sometimes very restless. Your most important task is to be more disciplined, so that you stick to a task long enough to get some real benefit from it. There is a real danger that your interest in any subject will be shallow. Another possible problem, which may seem less serious but is actually greater, is that you prefer to deal with the world through your mind rather than your feelings. This will keep you from really being in touch with some experiences in life - such as love and sensitivity to beauty - for which your mind alone is not enough. Also, you cannot really get in touch with other people through your mind alone. Unless you develop your emotions along with your mind, you may feel lonely and cut off from others. With your lively mind, you may enjoy playing practical jokes on people. This is fine if you are careful not to hurt people who are more sensitive than you.
