The greatest mistake you can make in life is to be continually fearing you will make one.
Everybody makes mistakes. That's why they put erasers on pencils.
Mistakes are as serious as the results they cause!
— Would you like to learn to tango, Donna?
— Right now?
— I'm offering you my services, free of charge. What do you say?
— I think I'd be a little afraid.
— Of what?
— Afraid of making a mistake.
— No mistakes in the tango, Donna. Not like life. It's simple. That's what makes the tango so great. If you make a mistake, get all tangled up, just tango on.
Knowing the wrongs couldn’t alter them.
— No, it's not an adventure, it's a mistake!
— Okay, yes, it's a mistake. I know it's a mistake. But there are certain things in life where you know it's a mistake but you don't really know it's a mistake because the only way to really know it's a mistake is to make the mistake, and look back, and say, "Yep. That was a mistake."
So, really, the bigger mistake would be to not make the mistake, because then you go your whole life not really knowing if something is a mistake or not.
— I dunno, you said mistake a lot.
Am I sorry for what I did? Well, are you? There's not a day goes by I don't feel regret. Not because I'm in here or because you think I should. I look back on the way I was then. A young... stupid kid who committed that terrible crime. I wanna talk to him. I wanna try and talk some sense to him, tell him the way things are. But I can't. That kid's long gone. This old man is all that's left. I gotta live with that. Rehabilitated? It's just a bullshit word.
