PART 1: Thoughts
What did we want readers to learn about expertise? What concepts and ideas were important to introduce? How should a readers ideas about training and potential be changed by reading this book?自己写作时也可以参照这些问题进行思考。
Obviously we needed to explain what deliberate practice is. How would we do that? Well, first we would need to explain how people normally practice and the limitations of that approach, and then we would discuss purposeful practice, and so on. At that point we were envisioning various approaches we could use to reach our goals for the book and weighing them, seeing which options seemed best. 本文的作者思路。
首先，作者举了专家医生症成功断出病人的病因的例子，说明主要因素不仅是因为他们拥有足够的医学知识，更重要的因素是专家们在多年的实践中已经建立起更复杂的整体知识体系，即更复杂心理表征，而缺乏经验的医生的心理表征还处在初级阶段，不会像专家们那样对问题进行加工分析，表明一个复杂的心理表征，会使这个过程变得更快更有效率。
再还结合刻意练习这本书的写作经历，他们先通过问题确定目标，建立起初始图像，构建大概的心理表征，再不断的细化建立高级心理表征，助于他们更好完成这本书。
并告诉我们心理表征和刻意练习的之间的关系，刻意练习的主要目的是发展有效的心理表征，心理表征是刻意练习关键部分之一。通过各种例子解释心理表征有助于我们高效学习，它让我们发现错误，磨练技能可以提高心理表征，而心理表征有助于磨练技巧，二者形成良性循环。
就像阅读原版书，起初自己只是看看，入群后开始写笔记，在大家点评和自己练习发现问题，然后修改，开始在自己的大脑建立起关于写作的心理表征雏形，再通过一步步练习，希望自己能越来越进步。总之，自己亲自实践练习很重要，构建起属于我们自己的心理表征，刻意练习形成高效心理表征，再通过产生的高效心理表征进行新一轮刻意练习，形成良性循环。
PART 2: Summary
Initially, the author illustrates the case of expert doctors to show they have built sophisticated mental representations in contrast with many less experienced doctor. So the experts can diagnoses the reason of the patient fast and precisely.
And,mental representations just one of the key part of deliberate practice, the main purpose of deliberate practice is to develop effective mental representations.Then, as to see how the authors write the book and other examples, we know the virtuous circle rules: honing the skill improves mental representation, and mental representation helps hone the skill. In short, we could practice our techniques to improve and sharpen our mental representations.
