* Why I still like traditional resource books and a list of recommended resource books, plus a fractals video recommendation.

* About having faith in what you do, not giving up, student apathy, why the work is not really just about the work, remembering that you cannot do it all yourself, making effort transparent, what makes a great teacher, modeling adult reactions, and how to raise effectiveness in the classroom.
