It is as sport to a fool to do mischief: but a man of understanding hath wisdom.

A fool shows his annoyance at once, but a prudent man overlooks an insult

With the ancient is wisdom; and in length of days understanding

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

My son, attend unto my wisdom, and bow thine ear to my understanding: / That thou mayest regard discretion, and that thy lips may keep knowledge.

Travel makes a wise man better, and a fool worse.
