Fair warning from:
A guy came up to me in a coffee shop the other day as I was grading papers. He started up a conversation (not like I was busy or anything), asking me what I taught. When I told him, he got all excited. He merely taught high school and was thinking of going back to graduate school to get his PhD so he could do some real teaching.
I looked him straight in the eye and told him not to do it. You’re better off where you are, I said. And I meant it.
Unlike Rebecca Schuman, however, I don’t regret earning my PhD. I just wouldn’t recommend that anyone else do what I did (a reverse categorical imperative?).
