Temperance tips from the king Lear’s fool

FOOL:

Have more than thou showest,
Speak less than thou knowest,
Lend less than thou owest,
Ride more than thou goest,
Learn more than thou trowest,
Set less than thou throwest;
Leave thy drink and thy whore,
And keep in-a-door,
And thou shalt have more
Than two tens to a score.

King Lear

Aristotle on moderation

Mankind, he used to say, was divided into those who were as thrifty as if they were going to live forever, and those who were as extravagant as if they were were going to die any moment.
