Some interesting thoughts about anger, worth to read:
Anger is implanted in us as a sort of sting, to make us gnash with our teeth against the devil, to make us vehement against him, not to set us in array against each other.
COLERIDGE
When anger rushes unrestrain'd to action, Like a hot steed, it stumbles in its way.
SAVAGE
Lamentation is the only musician that always, like a screech-owl, alights and sits on the roof of an angry man.
PLUTARCH
He is a fool who cannot be angry; but he is a wise man who will not.
SENECA
Men in rage strike those that wish them best.
SHAKESPEARE
Men often make up in wrath what they want in reason.
W.R. ALGER
Anger is the most impotent passion that accompanies the mind of man; it effects nothing it goes about; and hurts the man who is possessed by it more than any other against whom it is directed.
CLARENDON
When angry, count ten before you speak; if very angry, a hundred.
JEFFERSON
An angry man opens his mouth and shuts up his eyes.
CATO
When a man is wrong and won't admit it, he always gets angry.
