When you wake up in the morning, tell yourself: The people I deal with today will be meddling, ungrateful, arrogant, dishonest, jealous and surly. But I have seen the beauty of good, and the ugliness of evil, and I have recognized that the wrongdoer has a nature related to my own — not of the same blood or birth, but the same mind, and possessing a share of the divine. And so none of them can hurt me. No one can implicate me in ugliness. Nor can I feel angry at my relative, or hate him.
– Marcus Aurelius, Meditations
Marcus is saying to prepare yourself for the ugliness of situations and people you meet every day by reminding yourself that YOU just as often act and are perceived this way by others. So cut them some slack, Jason.
