earnestly and rapidly
...Thoreau's Journal: 13-Sep-1852
How earnestly and rapidly each creature, each flower, is fulfilling its part while its day lasts! Nature never lost a day, nor a moment. As the planet in its orbit and around its axis, so do the seasons, so does time, revolve, with a rapidity inconceivable. In the moment, in the eon, well employed, time ever advances with this rapidity. To an idler the man employed is terribly rapid. He that is not behind his time is swift. The immortals are swift. Clear the track! The plant that waited a whole year, and then blossomed the instant it was ready and the earth was ready for it, without the conception of delay, was rapid. To the conscience of the idle man, the stillness of a placid September day sounds like the din and whirl of a factory. Only employment can still this din in the air.
