A teacher once told me that at a parents' evening, she suggested that a particular child might think of pursuing a career as a teacher. The parent replied "I hope she can do much better than that!" Not terribly encouraging for the teacher - and indeed it is hard to think of a more worthwhile way to spend one's working life than educating children.
Looking around my own list of Catholic blogs, some of the most articulate and original are written by teachers. A new one that has come to my attention is Witness to Love by Radagast. There are some excellent articles there and I recommend it to you. The blog has a strong pro-life and pro-family emphasis.
