Epictetus emphasizes the importance of internal focus over external validation in his work, "The Enchiridion." He warns that seeking pleasure from the approval or attention of others leads to the deterioration of one’s life goals and overall purpose. Instead of striving for external admiration, one should cultivate a sense of contentment within themselves while embracing the philosophy of life.

He advises that to truly embody the role of a philosopher, one must prioritize self-perception above societal views. This inner fulfillment is what ultimately defines one's character and philosophical stance. Being content with one’s personal belief system is key to genuine happiness and tranquility.
