Constancy

Strict constancy's an overrated virtue:
A little flexibility can't hurt you.

Generosity

While greedy bastards grab bucks by the fistful,
The generous grow poorer and look wistful.

Chastity

Spurning forbidden fruit—peel, pulp, and juice—
The chaste know peace, but rarely reproduce.

Good Cheer

When grief and gloom are what you want, good cheer
Is nothing but a big pain in the rear.

Modesty

Though sometimes modesty's worth emulation,
It's worse than useless during copulation.

Sobriety

A certain charm inheres in strict sobriety
Until one ventures forth into society.

Humility

When talk is soft, there's no harm in the humble
Who, when shrill protest's called for, merely mumble.
