The wise man does at once

“A wise man gets more use from his enemies than a fool from his friends.”     Baltasar Gracian

“Never contend with a man who has nothing to lose.”     Baltasar Gracian

“At 20 a man is a peacock, at 30 a lion, at 40 a camel, at 50 a serpent, at 60 a dog, at 70 an ape, and at 80 nothing.”     Baltasar Gracian

“Even a fool, when he holdeth his peace, is counted wise: and he that shutteth his lips is esteemed a man of understanding.”     Proverbs 17:28 Bible

“True wisdom is less presuming than folly. The wise man doubteth often, and changeth his mind; the fool is obstinate, and doubteth not; he knoweth all things but his own ignorance.”     Akhenaton
