“Experience keeps a dear school, but fools will learn in no other, and scarce in that.”

“Most fools think they are only ignorant.”

“There are no fools so troublesome as those that have wit.”

“Fools make feasts and wise men eat them.”

“All highly competent people continually search for ways to keep learning, growing, and improving. They do that by asking WHY. After all, the person who knows HOW will always have a job, but the person who knows WHY will always be the boss.”

“Wise men don't need advice. Fools won't take it.”

“It is ill-manners to silence a fool and cruelty to let him go on”
