At work this placement needs a place where it can begin. Not propping up someone else's idea, not polishing, not refining — starting. I often see people with this placement among the founders of small companies, the heads of start-up units, the turnaround managers who get called in to haul something out of a hole and let go once it's stable again. Stability, on the whole, isn't their landscape.
It tends to come into its own in any work with a direct physical or sensory payoff. Coaches, surgeons, soldiers, rescue crews, athletes, chefs in a fast kitchen. Roles that reward quick decisions and personal responsibility for the outcome suit it. Bureaucratic structures with long chains of sign-off get one of two responses: the person bends them into their own shape, or leaves.
I'd single out one more category — trades where the result is visible at once. Welding, joinery, fixing machines, fitting and installation. Mars in Aries tends to want to touch what its hands have made by the end of the day. Long intellectual projects, where you won't see the upshot for a year, tend to wear it down.
In a team the person tends to be either the leader or the lone operator. The middle position — executing someone else's plan inside someone else's crew — rarely suits, because they start arguing with the manager and trying to take over the wheel. That's why many end up running their own thing in the end, even when it pays less, simply because there they get to decide for themselves.
Financially this is someone who tends to earn in bursts but saves poorly. Money arrives on the back of initiative and a good run of nerve, then leaves on new projects and on the spot. A steady budget comes hard, and usually needs a partner-bookkeeper at the elbow — someone who's comfortable saying 'no'. The single most useful money habit for this placement, in my experience, is learning to let one venture stabilise before chasing the next on a wave of feeling.
