"Why I Left Teaching Behind" by Sarah Fine (The Washington Post, 9 August 2009)
I feel much the same about teaching as Fine does, for many of the same reasons, especially as she discusses the current perception of teachers -- "the fact that," as she writes, "a portion of the American public sees teaching as a second-rate profession."
One of my least favorite quotes of all time is "Those who can, do; those who can't, teach." Because, please. The Simpsons says it best:
Dance Instructor: Marge, there's an old saying about those who can't
Dance Instructor: No, they go home. How can you teach if you can't
