If I only had the opportunity to learn from my mistakes, I would learn from them, but there are too many things that you can’t do twice: in reality, the most important things are things that you do not do twice, and therefore you can’t do them better next time. You do something badly, and you realize how well you could have done it, and you are willing to do it well. But the experience that follows is very different, and you make mistakes again. Being prepared for that same experience does not prepare you for the next one.
