“In peace there’s nothing so becomes a man as modest stillness and humility: but when the blast of war blows in our ears, then imitate the action of the tiger; stiffen the sinews, summon up the blood. Disguise fair nature with hard-favour’d rage; then lend the eye a terrible aspèct; let it pry through the portage of the head like the brass cannon; let the brow o’erwhelm as fearfully as doth a galled rock o’erhang and jutty his confounded base, swill’d with the wild and wasteful ocean. Now set the teeth and stretch the nostril wide; hold hard the breath, and bend up every spirit to his full height!” – William Shakespeare, King Henry V 3.1
