Ἔσω βλέπε· μηδενὸς πράγματος μήτε ἡ ἰδία ποιότης μήτε ἡ ἀξία παρατρεχέτω σε. - Marcus Aurelius

It is not death that a man should fear, but he should fear never beginning to live.

Some people, when they do someone a favor, are always looking for a chance to call it in. And some aren't, but they're still aware of it--still regard it as a debt. But others don't even do that. They're like a vine that produces grapes without looking for anything in return. (Hays translation)

From Rusticus...I learned to read carefully and not be satisfied with a rough understanding of the whole.
