In general, remember that sharing intimate details calls for people of faithfulness and sound principles; [24] and how easy is it to find people of that description today? Just point out to me, please, someone with the moral fibre to say, ‘I’m only interested in my own business, in what is inalienable, what is by nature free. This, the essence of the good, I hold secure; as for the rest, let it be as it is, it makes no difference to me.’
Discourses 4.13.23
The underlying Stoic issue here is the importance of focusing on what is within one's control and letting go of external events. As Epictetus notes, "what is inalienable, what is by nature free" (Discourses 4.13.24) is the key to living well. This phrase reveals that true freedom and security lie in one's character and principles, not in external circumstances. This insight suggests that to live well, one should prioritize their own moral fibre and focus on what they can control, rather than getting entangled in the affairs of others or worrying about things that are beyond their power to change. As Epictetus advises, one should strive to be someone who can say, "I'm only interested in my own business" (Discourses 4.13.24), meaning they are focused on their own character and actions. To apply this insight today, someone could reflect on their own priorities and ask themselves: What am I worrying about or investing my energy in that is outside of my control? How can I redirect my attention to my own character and principles, and focus on what is truly important to me? By doing so, they can cultivate a sense of inner freedom and security, and live more in accordance with their values. As you go about your day, consider: What is one thing you can let go of that is outside of your control, and instead focus on cultivating your own moral fibre?
