So I have no intention of leaving academia, and if I do it will be because I have been forced to in order to stay in New York (or California) or because I cannot make enough money or find enough time in academia to support and enjoy my family. These are real concerns, and I certainly think about them a lot, but I hope to continue to do well enough that I can over come them.
I wanted to link to an article by a professor who left academia for industry, and wrote about why he was doing it. Even though he is a computer scientist, and the fields are substantively different, I feel like his reasoning is applicable to all of academic science and is well worth reading and thinking about.
That essay, entitled "On leaving Academe", can be found here.
