“If a man didn't make mistakes he'd own the world in a month.
But if he didn't profit by his mistakes he wouldn't own a blessed thing.”

“He doesn't understand I want the freedom to make my own mistakes.”

“I daresay one profits more by the mistakes one makes off one's own bat than by doing the right thing on somebody's else advice.”

“…he knew there wasn't a soul in the mob he could trust – except perhaps Dallow. That didn't matter. You couldn't make mistakes when you trusted nobody.”

“The better a man is, the more mistakes will he make - for the more new things he will try. I would never promote a man into a top level job who had not made mistakes, and big ones at that. Otherwise he is sure to be mediocre.”

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

“He who does nothing makes no mistakes; he who makes no mistakes learns nothing.”

“Rain didn't make things messy. People did that all on their own.”

“If there is a god, why did he make me an atheist? That was his first mistake. Well, the talking snake was his first mistake.”

“One must make one's own mistakes”
