We all make mistakes which are inevitable. What makes mistakes worse is failure to correct your own mistakes. While making mistakes is good, repeating mistakes is definitely not. Apart from correcting your own mistakes, we should learn from the mistakes as well.

错误不可避免，最糟糕的是我们不纠正自己的错误。制造错误有好处，重复错误就不一定是对的，除了要纠正我们的错误，我们也要从错误中学习。
You can only learn from you admit you have made one. As soon as you start blaming other people, you distance yourself from any possible lesson that could be learned from it. Admission of mistake, even if only privately to yourself, make learning possible by moving the focus away from blaming yourself and towards understanding. Wise people admit their mistakes easily. They know progress accelerates when they do. On the other hand, for many reasons admitting mistakes is difficult. This is why some people consider that people can learn nothing from mistakes. We are educated in school, in our families, or at work to feel guilty about failure and to do whatever we can to avoid mistakes. This sense of shame combined with the inevitability of setbacks when attempting difficult things explains why many people give up on their goals: they are not prepared for the mistakes and failures they will face on their way to what they want.
你可以只从你已经承认的错误中学习，一旦你开始责备别人，你就会使自己远离那些可能从中学到东西的可能性。允许错误的产生，对于自己私下可能学到的教训，要是能够通过把焦点转移到责备自己并且走向理解层面那该多好啊。明智的人更容易接受他们的错误。他们知道做什么时能加速进步。这就是一些人思考人们在错误中学不到任何东西的原因。我们在学校中受教育，在家庭或者在工作中对失败感动愧疚，并尽我们所能来避免错误。当结合挫折的必然性解释了为什么很多人放弃了自己的目标：他们没有为他们想要走的路上遇到的错误和失败作准备。
In conclusion, we can and could learn good lessons from past mistakes in order to be more successful in our private and public lives.
总之，为了在我们私人和公共的生活中取得更多的成功，我们能从过去的错误中学到一堂很好的课。
