"Finally, from so little sleeping and so much reading, his brain dried up and he went completely out of his mind.” (Miguel de Cervantes Saavedra, Don Quixote)
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
