关于Economics Graduate Study and Research的一篇文章，当时读完就觉得很受益，现在已经是在phd项目的第三年了，回头再看一遍，又有很多感想，重新获得动力。作者是做“applied microeconomic theory”的，所以文章不会涉及到计量统计软件的应用等具体问题，但是文中的思想是不管做Theoretical还是Empirical都通用的，甚至对于life itself而言也是通用的吧。节选一段如下：
“I bet that, unless you are talking about the very, very top pioneers, the difference in
intelligence among most academics must be very small. What makes a good researcher is
one’s ability to lock the mind onto one problem. “Keep going,” “just keep going,” “keep
thinking about it,” “don’t give up.” These will serve you very well. Sir Peter Medawar, a
British Nobel laureate biologist was quoted as saying, "One does not have to be terribly
brainy to be a good scientist,” and "One would do better for owning some of those oldfashioned
virtues---application, diligence, a sense of purpose, the power to concentrate, to
persevere and not to be cast down by adversity."

So true!
