“Every event has two handles—one by which it can be carried, and one by which it can’t. If your brother does you wrong, don’t grab it by his wronging, because this is the handle incapable of lifting it. Instead, use the other—that he is your brother, that you were raised together, and then you will have hold of the handle that carries.”
Epictetus, Enchiridion, via The Daily Stoic (Page 180)
