什么是“忙碌低效”

很多人都会遇到这种现象，明明是忙碌了一整天，可是到头来感觉什么任务也没有完成，有时候既没有完成工作任务，也没有得到放松休闲，最终感觉一天就这么“浪费”过去了。

一言以蔽之，明明很忙碌，却几乎什么也没有产出。

这种现象在工作、生活中相当常见。

Kintsugi is the Japanese art of putting broken pottery pieces back together with gold — built on the idea that in embracing flaws and imperfections, you can create an even stronger, more beautiful piece of art.

这段历史的特征：混乱；王朝短命；

王朝短命的原因：

1. 群雄逐鹿，英雄并起
2. 功成名就，贪图享乐
3. 父辈英雄，儿孙狗熊
4. 汉族胡虏，此消彼长

It might not seem there’s much to learn about how to work hard. Anyone who’s been to school knows what it entails, even if they chose not to. There are 12 year olds who work amazingly hard. And yet when I ask if I know more about working hard now than when I was in school, the answer is definitely yes.

One thing I know is that if you want to do great things, you’ll have to work very hard. I wasn’t sure of that as a kid. Schoolwork varied in difficulty; one didn’t always have to work super hard to do well. And some of the things famous adults did, they seemed to do almost effortlessly. Was there, perhaps, some way to evade hard work through sheer brilliance? Now I know the answer to that question. There isn’t.

神咒曰：
天地玄宗，万炁本根，广修万善，证吾神通，三界内外，唯道独尊，身有金光，护映吾身，视之不见，听之不闻，包罗天地，养育群生，受持一遍，身有光明。三界侍卫，五帝司迎，万神朝礼，役使雷霆，鬼妖丧胆，精怪亡形。内有霹雳，雷神隐鸣，通慧交彻，五炁腾腾，金光速现，覆护真人。

When it comes to topics about choice, we are always told to follow our passion.

But recently in an interview, Marc Andreessen gave a different view:

Interviewer: If you could give some advice – career advice, or otherwise – to a smart 23-year-old American today, what would it be?

M.A.: Don’t follow your passion. Seriously. Don’t follow your passion. Your passion is likely more dumb and useless than anything else. Your passion should be your hobby, not your work. Do it in your spare time.

Instead, at work, seek to contribute. Find the hottest, most vibrant part of the economy you can and figure out how you can contribute best and most. Make yourself of value to the people around you, to your customers and coworkers, and try to increase that value every day.

It can sometimes feel that all the exciting things have already happened, that the frontier is closed, that we’re at the end of technological history and there’s nothing left to do but maintain what already exists. This is just a failure of imagination. In fact, the opposite is true. We’re surrounding by rotting incumbents that will all need to be replaced by new technologies. Let’s get on it.

如何提高英文的科研写作能力

作为一个科研工作者，在国际学术期刊上发表科研论文是与同行交流、取得国际影响的必经之路。有些国内的科学家，实验做得很漂亮，但常常苦恼于论文的写作力不从心，成为国际交流的一大障碍。本文从博主的亲身体验出发，给博士生、博士后、以及年轻的PI提供一个借鉴。文章最后做简短总结。

我大学时的同班同学都知道，那时我的英语不算好（英语四级考试仅为“良”），写作尤其糟糕。初到美国之时，对英文环境适应得很差，读一篇JBC的文章要五、六个小时，还常常不理解其中一些关键词句的意思,心里压力极大。

本文的主旨是解释如何做研究。我们提供的这些建议，对于研究本身（阅读、写作和程序设计）、理解研究过程以及开始研究（方法论、选题、选导师和情感因素），都是极具价值的。

这是什么？
并没有什么神丹妙药可以保证在研究中取得成功，本文只是列举了一些可能会对研究有所帮助的非正式意见。

目标读者是谁？
本文主要是为新入学的研究生而写。

如何使用？
要精读完本文，太长了一些，最好是采用浏览的方式。很多人觉得下面的方法很有效：先快速通读一遍，然后选取其中与自己当前研究项目有关的部分仔细研究。
本文被粗略地分为两部分。第一部分涉及研究者所需具备的各种技能：如阅读，写作和程序设计等等。第二部分讨论研究过程本身：即研究究竟是怎么回事，如何做研究，如何选题和选导师，如何考虑研究中的情感因素。很多读者反映，从长远看，第二部分比第一部分更有价值，也更让人感兴趣。

The 9 most effective ways to achieve PhD success

Writing a PhD is physically, intellectually and emotionally daunting. You may spend each day doubting yourself, not sure if you’re making the right choices and unsure whether you’ve got what it takes. During my life, I’ve helped thousands of PhD students like you. I want to share with you the nine most effective ways of achieving PhD success.

They should give you some fresh insight into what it means to be a PhD student and what it takes to achieve PhD success. They will also make you think differently about the way you work. Some you may be familiar with, but others may be new. As with everything, keep an open mind and ask yourself whether a particular tip would be useful in the context of your own research and way of working.
