Born at this point in Leo season
Picture someone born on July 31, early in Leo, when summer is still building and the sun is only starting to feel bold. They love making a room brighter, yet they hesitate when attention turns toward their own work. A friend asks them to lead a small project, and they say yes, then spend the week wondering whether they really deserve the role. Their birthday invites them to let their warmth show before every doubt has been answered.
