Mercury in Sagittarius

Mercury is in detriment in Sagittarius: the mind is broad, opinionated and better at the big picture than at the detail. It thinks in principles and speaks with conviction; tact is not its first instinct. This is a placement for teaching, publishing and travel — anywhere meaning matters more than precision. The work is to check the facts before the sermon.
