“The successful man will profit from his mistakes andtry again in a different way.”

“The failure and the success both believe in their hearts that they have accurately balanced points of view, the success because he's succeeded, and the failure because he's failed. The successful man tells his son to profit by his father's good fortune, and the failure tells his son to profit by his father's mistakes.”

“A man must be big enough to admit his mistakes, smart enough to profit from them, and strong enough to correct them.”

“It's said that a wise person learns from his mistakes. A wiser one learns from others' mistakes. But the wisest person of all learns from others's successes.”

“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.”

“Only a fool learns from his own mistakes. The wise man learns from the mistakes of others.”
