In the teachings of Epictetus in "The Enchiridion," he emphasizes the distinction between our responsibilities and the choices of others. He suggests that individuals should focus on performing their roles with integrity and diligence, but they do not have the authority to choose the roles that others must play in life. This perspective encourages a sense of personal accountability while acknowledging the autonomy of others.

By acting well in one's own part, one cultivates virtue and fulfills one's duties. However, the recognition that choosing one's role is the domain of others promotes a healthy detachment from outcomes that are beyond personal control. This philosophy invites individuals to accept their position while respecting the choices made by others, thus fostering harmony and reducing conflict in interpersonal relationships.
