Beware
Of entrance to a quarrel; but being in,
Bear 't that the opposed may beware of thee.
Give every man thy ear, but few thy voice;
Take each man's censure, but reserve thy judgment.
Costly thy habit as thy purse can buy,
But not express'd in fancy; rich, not gaudy;
For the apparel oft proclaims the man.
-- William Shakespeare (1564-1616), Hamlet
-- Act i, Sc. 3
