A few more rounds in the tank

“All the performances of human art, at which we look with praise or wonder, are instances of the resistless force of perseverance; it is by this that the quarry becomes a pyramid, and that distant countries are united with canals. If a man was to compare the single stroke of the pickaxe, or of one impression of the spade, with the general design and the last result, he would be overwhelmed by the sense of their disproportion; yet those petty operations, incessantly continued, in time surmount the greatest difficulties, and mountains are leveled and oceans bounded by the slender force of human beings.”
Samuel Johnson
