Born at this point in Aries season
Born on April 15, this person arrives in the late part of Aries, when the season's first fire has already been burning for weeks. Momentum comes easily here. A plan gets started, then the question shows up: is this still what I want, or just what I began? Their drive is real, but so is the habit of answering before the question is finished. Learning to wait a beat, and let other people finish, is the ongoing work of this birthday.
