“You should never be ashamed to admit you have been wrong. It only proves you are wiser today than yesterday”
“Never be ashamed to admit you were wrong. It only shows you are smarter today than you were yesterday.”
“A man should never be ashamed to own that he has been in the wrong, which is but saying in other words that he is wiser today than he was yesterday.”
“When you come to see you are not as wise today as you thought you were yesterday, you are wiser today.”
“If you realize you aren't so wise today as you thought you were yesterday, you're wiser today.”
“We should have been wiser; we should have died yesterday.”
