Depend upon it, it is better to learn how to live without being angry than to imagine one can moderate and control anger lawfully; and if through weakness and frailty one is overtaken by it, it is far better to put it away forcibly than to parley with it; for give anger ever so little way, and it will become master, like the serpent, who easily works in its body wherever it can once introduce its head.
--St. Francis de Sales, Introduction to the Devout Life
