Reflection............................

30.  When another's fault offends you, turn to yourself and consider what similar shortcomings are found in you.  Do you, too, find your good in riches, pleasure, reputation, or such like?  Think of this, and your anger will soon be forgotten in the reflection that he is only acting under pressure; what else could he do?  Alternatively, if you are able, contrive his release from that pressure.

-Marcus Aurelius,  Meditations,  Book X
