Stoic Snippets 61

One man, when he has done a service to another, is ready to set it down to his account as a favor conferred. 

Another is not ready to do this, but still in his own mind he thinks of the man as his debtor, and he knows what he has done. 

A third in a manner does not even know what he has done, but he is like a vine which has produced grapes, and seeks for nothing more after it has once produced its proper fruit.

—Marcus Aurelius, Meditations 5.6
