What it does well
Starts things other people are still discussing. Recovers from setbacks faster than almost any other sign.
Fire · Cardinal · ruled by Mars
♂ Mars in Aries ♈
Mars governs drive and anger — how you pursue and how you fight. In Aries, that function takes on initiative, appetite and the willingness to go first — a Cardinal Fire expression ruled by Mars.
Where it strains
Bores quickly, interrupts constantly, and treats patience as a personal insult.
Reading a placement properly
Mars in Aries describes a function in a style. It says nothing yet about where that plays out — for that you need the house, and the house needs a birth time. A placement read without its house is half a sentence.
