Born at this point in Aries season
Born late in the Aries season, on April 13, this person carries the sign's fire with a bit more staying power than the early days of spring suggest. The opening rush of starting something new has already passed, leaving the harder work of finishing. Plans get dropped when the excitement fades, then picked up again when a friend asks about them. Forward motion still feels natural, but now it asks for patience with the unglamorous middle.
