Born at this point in Sagittarius season
This person starts the season with a plan half made and a bag already packed. Early in the sign, the pull toward somewhere new arrives before the details are settled, so the first weeks feel bright and loose. Friends laugh at the next idea, yet the same restlessness that opens doors also leaves loose ends behind. Finding a steady place to return to is the real test of that fire.
Interpretation, not prediction.
