Astrology can tell you many things. Mercury rules the mind and can be seen in your style of writing.
What You Need
You will need your Mercury sign. Do a quick search for astrology natal chart generators to obtain it. I highly recommend that you get a professional Astrology chart reading done. Though one of your personal planets can tell you a lot about one area of your life, the natal chart on a whole will tell you so much more.
Here are the signs:
The Aries mind is quick and impulsive and this shows in the writing. The writing is creative and somewhat unusual. You are very expressive. May include notes of dry humor about. May be intrusive and argumentative in the writing, as well.
The writing is not something out of the ordinary and obscure. It's explained and adds lovely tones of feeling to the senses of the reader. You have practicality in mind while you're writing, which means it will reach a grander audience, if you choose.
Gemini Mercury, (First sign ruled by Mercury)
Versatile, you are able to write of many different subjects. You are responsive to the world around you and very curious. You truly wish to connect with the reader and let he/she see what you see through every word.
You write of home and explain how it affected you in your later life. You may not be so specific to let the reader know it is you that you are talking about. Cancer Mercury is the least confrontational and in this you probably hide your frustrations in your writing in clever ways.
The writing is colorful and dramatic- sure to get the attention of others. You may write of children and their vigor. Adventure stories and saving the day.
Virgo Mercury, (Second sign ruled by Mercury)
It's often the only place that you can communicate fully, in words. You may surprise, even shock, others that know you for you seem like such a different person in your writing. You are clever and your common sense reflects in witty prose that will have others reading a page more than once.
Your prose is very harmonious and has a rhythm, even. You wish to translate color into words and reach others with it's beauty. You prefer to compare things and weigh them out.
There is the scientific and dissecting qualities of your mind reflected in your words. People are compelled by the ways you describe things, it becomes real to them. You may be dark in your prose, even morbid. There is a mystery that allures others to read.
Philosophy and expansion are in the forefront in your writing. Many of you are fantasy writers, for you wish to write of foreign lands and may just make your own. Descriptions are colorful and sometimes even humorous.
Here structure is reflected in the prose. Responsibility and duty are major themes. Earthiness and practicality. Most of you have a fascination with the medieval period.
Eccentricity and invention are shown in your work. You wish to shock and surprise people with what you write. You've observed the actions of others keenly and so there is a truth translated that others didn't even know they could relate to.
You channel what you feel from your environment and in this your writing is elusive. You have a smooth and colorful style. It's enjoyable to read and highly artistic.
