Mars in Sagittarius: you act on conviction and inspiration
Mars is drive: how you go after what you want, and how you fight.
You act on conviction and inspiration. Your energy is expansive and enthusiastic, and sometimes you leap before you look. The growth is building stamina, not only spark.
Sagittarius is fire, mutable and ruled by Jupiter
The element sets the temperament: fire acts, earth builds, air connects, water feels. The modality sets the motion: cardinal starts, fixed holds, mutable adapts. The ruler is the planet that carries the sign’s agenda.
Your Mars may be in Sagittarius in one zodiac and not the other
The tropical zodiac is tied to the seasons; the sidereal zodiac to the stars. They have drifted about 24 degrees apart, almost a whole sign. So a planet in the first two-thirds of tropical Capricorn usually sits in sidereal Sagittarius, and a tropical Sagittarius Mars is often sidereal Scorpio.
Neither is wrong. The tropical chart describes how you meet the world; the sidereal chart is the sky as it actually stood. We read both, plus True Sky and the draconic chart, and make sense of all four as one picture.
