What it means
You want to act your own way, not “as is proper”; freedom and a shared cause with like-minded people add to your strength. Your decisions can be a surprise to everyone around. Anger comes from bans, control and stupid rules.
The flip side is stubbornness against any pressure, even reasonable pressure; it's hard to act on someone else's plan. Coldness in conflict: the conversation just stops.
This isn't about you if you feel calmer following the rules and bans and control don't anger 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 Aquarius
What should match. Recall your last three strong bursts of anger. At least two were over bans, control or “that's how it's done,” not over a personal hurt.
When it’s not about you. Two out of three were over hurt by a person — this isn't about you.
