What it means
Your main weapon is the word: argument, wit, sarcasm, long message threads. You have several things going at once, your interest jumps around, your hands and head are always busy. Many short trips and meetings.
The flip side is scatteredness: a lot is started, less is finished, and nervous energy gets in the way of sleep. In a quarrel it's easy to say more than you need to, just for the sake of a clever line.
This isn't about you if in an argument you tend to go quiet and prefer one thing at a time to several.
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 Gemini
What should match. Recall your last three quarrels. In at least two, your main weapon was words — argument, a barb, messages — not silence or a slammed door.
When it’s not about you. In two out of three you go quiet or walk away and words aren't needed — this isn't about you.
