For me, the hardest things to learn in life have been:
我最不想学习和接受的事情有：

Learning to admit I'm wrong. And not just admit it to myself, but openly find the people that showed me I was wrong and then thanking them. The task of admitting we're wrong is already hard enough, but when compounded by my own obligation to find the person and say, "Hey, you were right.  I was wrong."  Make it painful sometimes.  I would like to believe that I'm getting better, but it's a work in progress.
学着承认错误。不仅仅只是跟我自己承认错误，还有被别人指出了我的错误，我还要谢谢人家。承认错误的任务已经够艰难了，但是有时候我还必须去跟一个人说,“嘿，你是对的，我是错的。”有时候这很痛苦。我宁愿去相信我正在变好，但是要慢慢来。

In the same vein:  changing my mind. We are creatures designed to be stubborn. Being feisty, stubborn and willful kept our ancestors alive.  Being right was secondary.  We circle ourselves with people who agree with us, we surround ourselves with media and reading that confirms our biases.  It's really challenging to change our mind.  I'm learning to do it.  I am getting there because I spend immense effort in arguing against everything I believe and testing my assumptions as frequently as possible.
同样的还有一件事：改变我的想法。我们生来就很固执。争强好胜、固执，还有任性，都是代代相传的。是否正确还是次要的。我们和赞同自己的人组成小圈子，我们只听只读赞同我们偏见的媒体报道。改变我们的想法却是是个挑战。我正在学习。我就快成功了，因为我很努力地去争辩那些我相信的事情以及尽可能频繁地去验证我的设想。

Learning to let go.  It's hard. We innately want eternity.  Our religions are obsessed with this:  "Don't worry, this isn't just a short life.  You've got eternity later."  We loathe the notion that we're here then gone.  I'm learning to let go of that delusion.  I'm here, then I'm gone.
学会放手。这很难。我们生来就很执着。我们的信仰就是：“别担心，生命很长，你会得到永生的。”我们极其反感那种我们很快就会消失的观念。我正试着从那种错觉当中放手。活在当下。
