Born at this point in Scorpio season
Born early in Scorpio, this person arrived while the season was still gathering its intensity. The first decan falls under Mars, so the urge to act and push a plan forward can feel close to the surface. At times that shows up as a habit of finishing what was started. The same drive can make waiting feel hard, especially when a situation moves slower than the effort behind it. Noticing that friction is a fair place to begin.
