Does what's happened keep you from acting with justice, generosity, self-control, sanity, prudence, honesty, humility, straightforward ness, and all other qualities that allow a person's nature to fulfill itself? So remember this principle when something threatens to cause you pain: the thing itself was no misfortune at all; to endure it and prevail is great good fortune.
Marcus AureliusRun down the list of those who felt intense anger at something: the most famous, the most unfortunate, the most hated, the most whatever: Where is all that now? Smoke, dust, legend...or not even a legend. Think of all the examples. And how trivial the things we want so passionately are.
Marcus Aurelius
