Quotation from: The Prince

Written by: Niccolo Machiavelli

A prince, therefore, ought always to take counsel, but only when he
wishes and not when others wish; he ought rather to discourage every one
from offering advice unless he asks it; but, however, he ought to be
a constant inquirer, and afterwards a patient listener concerning the
things of which he inquired; also, on learning that any one, on any
consideration, has not told him the truth, he should let his anger be
felt.
