We are often deterred from crime by the disgrace of others.
Jokes aside, let us turn to serious matters.
Lighten grief with hopes of a brighter morrow; Temper joy, in fear of a change of fortune.
A word, once sent abroad, flies irrevocably.
The short span of life forbids us to spin out hope to any length. Soon will night be upon you, and the fabled Shades, and the shadowy Plutonian home.
Don't just think, do.
