years are made up of moments

“‘Ah!’ said the Count to Henri, awaking from his deep reverie, ‘how the scene is changed since last I saw it! I was a young man, then, and the Marchioness was alive and in her bloom; many other persons were here, too, who are now no more! There stood the orchestra; here we tripped in many a sprightly maze–the walls echoing to the dance! Now, they resound only one feeble voice–and even that will, ere long, be heard no more! My son, remember, that I was once as young as yourself, and that you must pass away like those, who have preceded you–like those, who, as they sung and danced in this once gay apartment, forgot, that years are made up of moments, and that every step they took carried them nearer to their graves. But such reflections are useless, I had almost said criminal, unless they teach us to prepare for eternity, since, otherwise, they cloud our present happiness, without guiding us to a future one.”
