“We learn a lot from the mistakes of others, but even more from our own.”

“Although we all make mistakes in life, the problems occur when we try to hide our mistakes, to cover them up rather than to learn from them and allow other people to learn from them.”

“We learn, when we learn, only from experience, and then we only learn from our mistakes. Our successes only serve to reinforce our superstitions.”

“Smart people learn from their mistakes. But the real sharp ones learn from the mistakes of others.”

“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.”

“It is better to learn from the mistakes of others than that others should learn from you.”
Te de aliis, quam alios de te suaviu’st.

“We should learn from the mistakes and experiences of others, particularly from those less knowledgable than we are. If our experiences are not grounded in reality, our decisions can never be correct.”

“We all mess up. It's what we learn from our mistakes that matters.”

“Learning to be wise has a deeper purpose than just learning to be smart. To become wise, we must learn to understand and master things we do not know. Learn from the mistakes we make ourselves. Learn from the mistakes other people make, and find out how other people achieved success.”

“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.”
