二 summary
Peak: secrets from the new science of expertise is a book about learning methods. The chapter 1 and chapter 2 are the introductory parts which serve the function of introducing the concept "deliberate practice".
Chapter 1 cites some examples to illustrate that we are all talents if we practiced adequately. But this kind of practice is purposeful practice,not naive practice. Then the authors demonstrate four features of purposeful practice leading us to success. However, what is the basic principle of purposeful practice(deliberate practice)?
This basic principle is adaptability of our brains. Just as we do exercise to be muscular, so we can work our brains to improve brains' structures and functions. How to work our brains? Deliberate practice! Therefore, chapter 2 lays the theoretical foundations for chapter 1.
三 中文感悟
我们非常羡慕生活中的一些“天才”，可天才都是因天赋异禀而成为天才吗？这本书在开头就告诉我们：当然不是。那凭借的是什么？是练习。是purposeful practice，进一步实现最终的目标deliberate practice。这与我们平常的naive practice有很大不同。
再想想现实生活中的我们，常常听到这样的话：我没有天赋，我肯定做不好...我应该绕道而行。通过读这本书的前两章，使我觉得这个说法真的是一种可笑的逃避的婉辞。文章的前两章通过大量的例子使我认识到，我们的大脑具有无限的可能。我觉得我自身就缺少这种purposeful或是deliberate练习。我在平常会进行practice，可就是东忙一头，西忙一头，最后没有任何效果，通过这一周，使我认识到我要改变自己practice的方式。
