2) 以为知道该干什么，结果做错了

) 做对了，但努力不够

4) 非常努力但努力得不够久

任何领域的卓越成就都只能通过一生的努力来获得；稍低一点的代价也换不来。 ”（Excellence in any department can be attained only by the labor of a lifetime; it is not to be purchased at a lesser price.）为什么要那么久呢？答案是，因为有些阶段就是无法跨越。

浪费时间的最有效方法并非无所事事，而是“真诚地做错事”。

在选择该做什么的时候，一个屡试不爽的判断依据是，慎选“容易的”，别怕“困难的”。

人们往往拒绝做一些实际上有意义的事情，是基于“实用主义”。实际上，学习永远是无本万利、稳赚不赔的活动（也许有人不同意，这事儿实在难以争论）。很多人习惯于在行动之前一定要问一个“做这事情有什么用？”尽管这本身通常是没有错的，但是，在学习的时候问这个问题就很可能是不明智的了。

第一类读者只想了解一下这篇论文是不是对他有用，这时候论文摘要就很重要。

第二类读者，他们只对该论文的中心论点或者/和论文的历史有兴趣，而对里面的细枝末节可能没什么兴趣，这类读者愿意花些时间读文章的一两段概述。

第三类读者，对整篇文章的每个细节都感兴趣

关键是要记住“多替别人着想”这个原则。

1．    概述部分不要夸大其辞，过于吹嘘正文的内容。这是很糟糕的形式，你早晚会后悔的。 2．    恰当地指出他人的贡献和成就，不要太吝啬了。 3．    不要把一篇论文写成大同小异的三篇论文，你可以用一份好的PPT做几次演讲，但是把本质上是一篇的论文发表几次是很糟糕的事情。 4．    不要一稿多投，以为这样就可以增加接收的可能性。这是很不道德的，浪费了评审人的宝贵时间，要知道大家的时间都非常紧张。编辑们对此恨之入骨。不幸的是，至少在我熟悉的那些领域，中国作者因为这种事情在国际上已经声名狼藉了。

As you can see from above, it is certainly possible to have a good collaborative filtering system without a recommendation engine

Collaborative Filtering (Wikipedia definition) is a mechanism used to filter large amounts of information by spreading the process of filtering among a large group of people.

The important thing, one that not many social sites realize, is that a (CF) system that doesn't automatically match content to your preferences, is inherently flawed. The reason for this is simple: Unless you can achieve perfect diversity and independence of opinion, one point of view will always dominate another on a particular platform. The dominant point of view on the social web is a left-leaning one, and without the ability to get the most appropriate pieces of content to the people that care most about them, the right-wing point of view gets buried almost every time.

Money is the poor man’s credit card.

The car has become the carapace, the protective and aggressive shell, of urban and suburban man.

Why is it so easy to acquire the solutions of past problems and so difficult to solve current ones?

The trouble with a cheap, specialized education is that you never stop paying for it.

The future of the book is the blurb.

"I may be wrong, but I’m never in doubt.”

Politics offers yesterday’s answers to today’s questions.

When all men think alike, no one thinks very much.

参考文献要靠平时积累。 平时不多读东西，不作规范的读书笔记，下笔需要引证时就抓瞎了
