Mercury in the 10th house

The 10th house is career, standing and public role. Mercury here is known for what it says. Teaching, writing, journalism, law, sales and analysis are common, and reputation rests on communication rather than on title. These people are quotable, and their words travel further than they expect. The 10th house cusp moves with the clock, so a planet this close to it needs an accurate birth time. The exposure has a cost: one careless sentence outlasts a careful year.
