Mercury in the 3rd House
Sharpens intellect, writing ability, and communication skills considerably. The individual thrives in media, journalism, or any field requiring mental agility and verbal dexterity.
You figure things out by writing about them. Reading back what you wrote is how you find out what you believed.
Thinking alone does not quite work for you. You can feel something, you can sense around the edges of an opinion, but until you put it on a page the thing stays blurry. Then you start writing, and the writing surprises you. Sentences come out that you did not know you had. By the time the paragraph is done, you have an opinion that was not fully formed before you started. This has happened to you a thousand times. You have stopped being surprised by it, but you have not stopped relying on it.
The other thing is your siblings or whoever functioned as siblings. They were probably part of how you learned to communicate. Maybe you fought with words instead of fists. Maybe you and a cousin invented a private shorthand that still shapes how you write. Either way, the people closest to you in age became the first audience for your thinking, and they are still the audience you write toward without meaning to.
Your Mercury is in its own house, the 3rd, the house of courage, communication, siblings, and the short-form thinking that makes up most of your real interior life.
