摘录+感悟
1.But while the abilities are extraordinary, there is no mystery at all about how these people developed them. They practiced. A lot.
这里举了许多有非凡才能的人士的例子，但是明确告诉我们他们并不是有特殊的天分（或者可能有，但并非仅靠天分），而是依靠大量练习才能练好技能。
2.I have found that no matter what field you study, music or sports or chess or something else, the most effective types of practice all follow the same set of general principles. There is no obvious reason why this should be the case. Why should the teaching techniques used to turn aspiring musicians into concert pianists have anything to do with the training that a dancer must go through to become a prima ballerina or the study that a chess player must undertake to become a grandmaster? The answer is that the most effective and most powerful types of practice in any field work by harnessing the adaptability of the human body and brain to create, step by step, the ability to do things that were previously not possible.
二十世纪以来，在许多技能领域又有了比之前更大的突破，并不是这个年代出生的人整体比之前的人有什么特殊之处，而是许多领域有了卓有成效的练习方法，并且这些人运用了这种练习方法。作者通过研究告诉我们在技能学习这方面是有着普适性原则的——逐渐训练自己的身体和大脑的适应性以做到之前无法做到的事情。
3.But there is one very important thing to understand here: once you have reached this satisfactory skill level and automated your performance—your driving, your tennis playing, your baking of pies—you have stopped improving.
作者举了一个学习打网球的例子来说明我们一般的学习步骤，学一个动作——练习——觉得学的不错——学一个新动作——练习——觉得学的不错——学另一个新动作......如此循环往复，并且在这一过程中当掌握了最小必要技能之后就上场练习，同时自己的动作达到automatic，然后继续打比赛，大多数人都只能达到一个“还过得去”的中等水平——可以上场玩但是总有瓶颈，永远称不上高手。他的表述令我心惊you have stopped improving，停滞不前。其实对大多数人而言，在非专业技能领域这种水平足矣，之后再写这一点。
4.But no. Research has shown that, generally speaking, once a person reaches that level of“acceptable”performance and automaticity, the additional years of“practice”don’t lead to improvement.
一个事实是开车二十年的司机水平有可能不如开车五年的司机。人们的某些技能，如果不经刻意练习，并不会如我们所愿随着时间和使用频次的增加自然而然提高。
下面就要开始谈研究得出的方法了，明天继续~
