A question I’ve been wrestling with lately, and one that surely has come up before, is what to think about in graduate school. On one hand, if there were ever a time to be single-mindedly devoted to one subject, this is the time. Every spare amount of intellectual energy, in this view, ought to be devoted to (in my case) economics. On the other hand, an intellectually curious person has trouble behaving this way. I think it’s good for the brain to have other pursuits to keep it in prime condition.
I can imagine the correct proportion is somewhere in the middle, I just haven’t figured out where yet.
