December 7 in profile
Fifteen degrees is the midpoint of Sagittarius, the sign as settled as it gets: frank, curious, ruled by expansive Jupiter. Aries, the sub-sign of this decan, brings Mars and a taste for effort. A December 7 Sagittarius likes a big aim but also likes sweating for it. The middle degrees keep the fire steady rather than explosive, so the energy goes into long efforts more than sudden bursts. Philosophy and stamina meet in this stretch.
Stress shows first as speed. They talk faster, cut people off and take on one more task to prove things are under control. Then comes a sudden blunt remark that surprises them as much as the listener. The fix they reach for is movement: a run, a cycle home, a loud playlist in the car. Stillness under pressure is hard work for them. Friends learn to suggest a walk rather than a talk.
At work they are best given a mission and left alone with it. They sell ideas well, rally a team before a launch and cope with travel and change better than most. Detail slips when the vision is exciting. Pairing up with a careful colleague helps, especially if they treat the checklist as part of the adventure rather than a chore.
