“Be not ashamed of mistakes and thus make them crimes.”

“Be proud of your mistakes. Well, proud may not be exactly the right word, but respect them, treasure them, be kind to them, learn from them. And, more than that, and more important than that, make them. Make mistakes. Make great mistakes, make wonderful mistakes, make glorious mistakes. Better to make a hundred mistakes than to stare at a blank piece of paper too scared to do anything wrong.”

“All men make mistakes, but a good man yields when he knows his course is wrong, and repairs the evil. The only crime is pride.”

“I don't want to give advice to a 19-year-old, because I want a 19-year-old to make mistakes and learn from them. Make mistakes, make mistakes, make mistakes. Just make sure they're your mistakes.”

“Leaders make a lot of mistakes but they admit those mistakes to themselves and change because of them.”

“I have since often observed, how incongruous and irrational the common temper of mankind is, especially of youth ... that they are not ashamed to sin, and yet are ashamed to repent; not ashamed of the action for which they ought justly to be esteemed fools, but are ashamed of the returning, which only can make them be esteemed wise men.”
