“One person, on doing well by others, immediately accounts the expected favor in return. Another is not so quick, but still considers the person a debtor and knows the favor. A third kind of person acts as if no conscious of the deed, rather like a vine producing a cluster of grapes without making further demands, like a horse after its race, or a dog after its walk, or a bee after making its honey. Such a person, having done a good deed, won’t go shouting from rooftops but simply moves on to the next deed just like the vine produces another bunch of grapes in the right season.”

Marcus Aurelius, Meditations, via The Daily Stoic (Page 210)
