from Euripedes’
This is spoken by Heracles’ old father at one point:
“Our lives, old friends, are but a little while,/ So let them run as sweetly as you can,/ And give no thought to grief from day to day/ For Time is not concerned to keep our hopes/ But hurries on its business, and is gone.”
I must say this rings a bell for me. (And it sounds a lot like Omar Kyhamm, doesn’t it? As in:
‘The bird of youth has but a little time/To fly, and lo, the bird is on the wing.”
