“I'll never make the mistake of being 70 again.”

“Being not perfect is not about making mistakes and saying I'm sorry, but! its about learning from it and then being perfect for not making the same mistake again.”

“I can't promise you that I'll never be am asshole again. But I can promise you that I don't mean it. And I can't promise you that I won't ever make mistakes, but I can promise you that I'll learn from them and do whatever it takes to make it right with you again.”

“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.”

“I make mistakes; I'll be the second to admit it.”

“But then again, I was pretty certain I'd make more mistakes, so I didn't dwell on the one I'd just made too long. This is another thing I'll put in my arsonist's guide: if you make a mistake, don't dwell on it too long, because you'll make more of them.”
