Theodore Roosevelt on anger

Speak softly and carry a big stick.

To announce that there must be no criticism of the president, or that we are to stand by the president right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public.

It is not the critic who counts: not the man who points out how the strong man stumbles or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself for a worthy cause; who, at the best, knows, in the end, the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat.

Anybody can become angry⁠—that is easy, but to be angry with the right person and to the right degree and at the right time and for the right purpose, and in the right way⁠—that is not within everybody’s power and is not easy.

Aristotle384–322 BC

I was angry with my friend I told my wrath, my wrath did end. I was angry with my foe: I told it not, my wrath did grow.

William Blake1757–1827A Poison Tree (1794), Songs of Experience (1794), A Poison Tree, st. 1In context

Holding on to anger is like grasping a hot coal with the intent of throwing it at someone else; you are the one who gets burned.

Gautama Buddha501–501 BC
