Mercury in Aries traits

Fast, blunt and decisive, Mercury in Aries is read as a mind that reaches conclusions before the question is finished. People with it tend to think on their feet, argue with relish and say exactly what they mean. They're quick learners when something grabs them and impatient with long explanations, endless meetings and anything that feels like stalling. Their first idea is often their best, and they'd rather act on it and fix it later than plan forever. The blind spot is listening: they can interrupt, jump to conclusions or win an argument while missing the point. Pausing for three seconds before replying is a small habit that changes a lot for them.
