What it means
Your strength is well spent on the concrete: setting up, fixing, calculating, bringing things to precision. Your capacity for work is high, especially when it's clear why. You're angered by carelessness — other people's incompetence, mess, inaccuracy.
The flip side is nitpicking and anxious fuss: it's hard to stop until it's perfect, and anger is expressed as criticism of small things. Rest without a task comes hard.
This isn't about you if mess and other people's mistakes don't irritate you and work done “roughly” suits you.
How to check it on yourself
Check it against your past — write your answer down before you look at the chart.
If your Mars is in Virgo
What should match. Recall your last three irritations at work or at home. At least two were over carelessness: done sloppily, inaccurately, out of order.
When it’s not about you. Two out of three were over something else, and carelessness doesn't bother you — this isn't about you.
