“A wise man can learn more from a foolish question than a fool can learn from a wise answer.”
“Learning makes the wise wiser and the fool more foolish”
“Only a fool learns from his own mistakes. The wise man learns from the mistakes of others.”
“We can learn much from wise words, little from wisecracks, and less from wise guys. ”
“It takes a wise man to learn wisdom from a wise woman!”
“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.”
