The mind never puts forth greater power over itself than when, in great trials, it yields up calmly its desires, affections, interests to God. There are seasons when to be still demands immeasurably higher strength than to act. Composure is often the highest result of power. Think you it demands no power to calm the stormy elements of passion, to moderate the vehemence of desire, to throw off the load of dejection, to suppress every repining thought, when the dearest hopes are withered, and to turn the wounded spirit from dangerous reveries and wasting grief, to the quiet discharge of ordinary duties? Is there no power put forth, when a man, stripped of his property, of the fruits of a life's labors, quells discontent and gloomy forebodings, and serenely and patiently returns to the tasks which Providence assigns?
— William Ellery Channing (1780-1842)
Our life is frittered away by detail. An honest man has hardly need to count more than his ten fingers, or in extreme cases he may add his ten toes, and lump the rest. Simplicity, simplicity, simplicity! I say, let your affairs be as two or three, and not a hundred or a thousand; instead of a million count half a dozen, and keep your accounts on your thumb-nail. In the midst of this chopping sea of civilized life, such are the clouds and storms and quicksands and thousand-and-one items to be allowed for, that a man has to live, if he would not founder and go to the bottom and not make his port at all, by dead reckoning, and he must be a great calculator indeed who succeeds. Simplify, simplify. Instead of three meals a day, if it be necessary eat but one; instead of a hundred dishes, five; and reduce other things in proportion.
— Henry David Thoreau, Walden (first published August 9, 1854)
