"Let any man make a calculation of his existence, subtracting the hours in which he has been thoroughly happy—really and entirely at his ease, without one arriere pensée to mar his enjoyment—without the most infinitesimal cloud to overshadow the brightness of his horizon. Let him do this, and surely he will laugh in utter bitterness of soul when he sets down the sum of his felicity, and discovers the pitiful smallness of the amount. He will have enjoyed himself for a week or ten days in thirty years, perhaps. In thirty years of dull December, and blustering March, and showery April, and dark November weather, there may have been seven or eight glorious August days, through which the sun has blazed in cloudless radiance, and the summer breezes have breathed perpetual balm. How fondly we recollect these solitary days of pleasure, and hope for their recurrence, and try to plan the circumstances that made them bright; and arrange, and predestinate, and diplomatize with fate for a renewal of the remembered joy. As if any joy could ever be built up out of such and such constituent parts! As if happiness were not essentially accidental—a bright and wandering bird, utterly irregular in its migrations; with us one summer's day, and forever gone from us on the next!"
