“We can learn much from wise words, little from wisecracks, and less from wise guys. ”
“A wise man can learn more from a foolish question than a fool can learn from a wise answer.”
“Wise is the one who learns from another´s mistakes. Less wise is the one who learns only from his own mistakes. The fool keeps making the same mistakes again and again and never learns from them.”
“It takes a wise man to learn wisdom from a wise woman!”
“While it is wise to learn from experience, it is wiser to learn from the experiences of others.”
“A smart person learns from his mistakes, but a truly wise person learns from the mistakes of others.”
