I am less affected by their heroism who stood up for half an hour in the front line at Buena Vista, than by the steady and cheerful valor of the men who inhabit the snow-plow for their winter quarters; who have not merely the three-o'-clock-in-the-morning courage, which Bonaparte thought was the rarest, but whose courage does not go to rest so early, who go to sleep only when the storm sleeps or the sinews of their iron steed are frozen.
Henry David ThoreauIf I choose to devote myself to certain labors which yield more real profit, though but little money, they may be inclined to look on me as an idler.
