Part 1: Summary
When you are pushed out of your comfort zone, the body responded by getting strong enough to establish a new comfort zone.A new homeostasis have been reestablished.But if you push too far outside your comfort zone, you risk injuring yourself and actually setting yourself back.The most effective forms of practice increase your ability to play rather than help you learn to play a certain instrument.Regular training leads to changes in the parts of the brain that are challenged by the training. We still have chance to improve ourselves though we think that we are "good enough".
Part 2: My thoughts?
沒有什么是不可能的?
通過第一和第二章節的閱讀學習,對傳統的訓練方式和有目的的實踐,還有刻意練習的思想有了一定的了解。書中提到好多觀念對我的沖擊不小：其中說到人腦的能力并不是fixed的，我把這里的fixed理解為局限的，也就是說，人的潛力是無窮的。
文中提到利用刻意練習的方法，不斷跳出舒適區，在人的自適應性作用下，你會通過達到一個個更高能力的平衡狀態或者是一種和諧的共同繁榮，從而提高自身的水平。現在的問題是，你很難有一個標準去界定你的能力上限在哪里：你不敢去想，否定自己，自然你也就沒有做這件事情的信心和行動力。
就和文章中提及的背電話號碼一樣，在一般人的眼中，這件事情的上限就是7-9位數字。而通過訓練的方法，成功將這個數字提高到41位。很多時候，你也不知道你的能力上限在哪里，你不敢逃離出這個一般人眼中的上限——也就是一種舒適區。逃離這個舒適區所花費的代價也許不值得你這么做，自然就沒有人嘗試，也就是說缺乏行動力！當自身判斷收獲小于付出的時候，你也很難通過這種練習，來獲得提高，或者說你也無法堅持下去。
當然，作者為我們提供了一個很好的視角：發現不足，通過行動去彌補、提高自己。沒有突破自己的舒適區的勇氣，你也很難體會到“會當凌絕頂，一覽眾山小”的樂趣！
Actions speak louder than words.
Part 3: Words and Expressions
Recipe
He was like the pianist playing the same songs the same way for thirty years. That is a recipe for stagnation, not improvement.
be a recipe for something中的recipe原意是“食譜” “配方”，在這里表示“原因”
表意遞進
What is not natural is a true dead-stop obstacle, one that is impossible to get around, over, or through.
這里的get around, over, or through: get around, get over和get through都有“克服困難”的意思。作者連用三個get有關的短語來強調不同的困難程度。
E.g.：Don't just think about it! Think over it! Think through it.?
One way or another
The sorts of practice that most people have already experienced in one way or another.
One way or another的意思是“用這樣或那樣的方式”，也就是“無論如何”，例如我們想表達“不擇手段”的時候就可以用到這個詞
E.g.: Some people archive their ambitions in one way or another.
Obscure
The idea for the study had come from an obscure paper I had discovered while searching through old scientific studies
obscure這個詞主要有兩個意思，一個是“晦澀難懂的”，一個是“鮮為人知的“，在這里取第二個意思。英國作家哈代寫過一本書叫《無名的裘德》，英文名字就是Jude the Obscure。
表才華能力的同義詞
exceptional, extraordinary;?
gift, talent, facility.
How far you travel along that path is up to you. Fighting!
