In "The Golden Sayings of Epictetus," the philosopher emphasizes the importance of personal responsibility for one’s own happiness. According to Epictetus, individuals often attribute their unhappiness to external circumstances, but he argues that it is one's own perspective and choices that lead to such feelings. He encourages people to recognize that they hold the power to change their mindset.

Moreover, Epictetus asserts that God has created humanity to experience joy and stability in life. Therefore, when someone finds themselves unhappy, it serves as a reminder that the source of that discontent lies within themselves. The philosopher’s teachings advocate for self-reflection and the understanding that true contentment comes from within, not from external factors.
