Context: Some day no one will have to work more than two days a week... The human being can consume so much and no more. When we reach the point when the world produces all the goods that it needs in two days, as it inevitably will, we must curtail our production of goods and turn our attention to the great problem of what to do with our new leisure.

“A day of worry is more exhausting than a day of work.”

Light (1919), Ch. XIX - Ghosts
Context: Among some papers on my table I see the poem again which we once found out of doors, the bit of paper escaped from the mysterious hands which wrote on it, and come to the stone seat. It ended by whispering, "Only I know the tears that brimming rise, your beauty blended with your smile to espy."
In the days of yore it had made us smile with delight. To-night there are real tears in my eyes. What is it? I dimly see that there is something more than what we have seen, than what we have said, than what we have felt to-day. One day, perhaps, she and I will exchange better and richer sayings; and so, in that day, all the sadness will be of some service.

“Try to work so hard for your benefit that you can compress a week into one day.”

“Two or three days at sea are equivalent to at least as many weeks on shore.”
