Mars in Capricorn is how you act and how you fight embodied, deliberate, durable.
Capricorn Mars acts patiently. The drive is steady, the anger slow to surface and slow to leave. You wear opponents down by outlasting them. Sex and effort both run on stamina. Your cardinal tends to start things — to initiate, to push the first move, which colours how this Mars actually shows up day to day.
The shadow: misplaced rage, chronic procrastination (energy held in the body without release), or fighting the wrong battle to avoid the right one. The work is friendship with your own desire.
Practice: name one thing you actually want this month — not should-want. Take one visible step toward it. Mars does not grow until it is used.
