What it means
Your manner is quick, energetic, sometimes sharp: people feel your drive before you say anything important. Life moves best through your own initiative, not through waiting. Your body needs sport and movement.
The flip side is that you come across as sharper than you are, and conflicts find you on their own; haste leads to bruises and cuts more often than for others. It's hard to wait for others to decide for you.
This isn't about you if the first impression of you is softness and calm and you usually leave initiative to others.
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 the 1st house
What should match. Ask two or three acquaintances about their first impression of you. At least two will name drive, energy or sharpness, not softness and calm.
When it’s not about you. Two out of three will recall softness and calm — this isn't about you.
