If you are pained by any external thing, it is not this thing that disturbs you, but your own judgment about it. It is in your power to erase this judgment about it. If anything in your own nature gives you pain, you are who hinders you from correcting your opinion.
Marcus AureliusDig inside. Inside is the fountain of good, and it will forever flow, if you will forever dig.
Marcus AureliusEnough of this wretched life and murmuring and apish tricks. Why art thou disturbed? What is there new in this? What unsettles thee? Is it the form of the thing? Look at it. Or is it the matter? Look at it. But besides these there is nothing. Towards the gods, then, now become at last more simple and better. It is the same whether we examine these things for a hundred years or three.
Marcus Aurelius
