Born at this point in Aries season
This person was born in the last stretch of the Aries season, when the early push of spring has mostly turned into work that needs finishing. Plans made in the first weeks now ask for patience. Some days the urge to start something new comes back, and the old project looks tired. Finishing a thing that no longer feels new takes a different kind of courage, and this person has to decide which fights are still worth the effort.
