For man always looked to hire a fool to amuse him without knowing he was one all along.

And hope was an oath I swore never to take.

If thou hast never been a fool, be sure thou wilt never be a wise man.

At thirty man suspects himself a fool; Knows it at forty, and reforms his plan; At fifty chides his infamous delay, Pushes his prudent purpose to resolve; In all the magnanimity of thought Resolves; and re-resolves; then dies the same

The cleverest of all, in my opinion, is the man who calls himself a fool at least once a month.

There is only a finger's difference between a wise man and a fool.
