We do not have control over the things that happen around us, but what we do have is control over how we think and respond to those events.
Epictetus opens his Enchiridion with, “Some things are in our control, while others are not. We control out opinion, choice, desire, aversion, and , in a work, everything of our own doing. We don’t control our body, property, reputation, position, and ,in a word, everything not of our own doing. Even more, the things in our control are by nature free, unhindered, and unobstructed, while those not in our control are weak, slavish, can be hindered and are not our own.” [1.1-2]
Best of all, an honest understanding of what is without our control provides clarity about the world, all we have is our own mind.
