I recently came across this saying:
“A society grows great when old men plant trees the shade of which they know they will never sit in.”
I initially read it was a Greek proverb but its origin and attribution are in question (https://www.roger-pearse.com/weblog/2017/08/26/a-society-grows-great-when-old-men-plant-trees-in-whose-shade-they-know-they-shall-never-sit-an-ancient-greek-proverb/comment-page-1/).
Nonetheless I think it’s a brilliant thought worth remembering.
