And in the end,
Here is a secret hidden in plain sight: good teaching cannot be reduced to technique; good teaching comes from the identity and integrity of the teacher. In every class I teach, my ability to connect with my students, and to connect them with the subject, depends less on the methods I use than on the degree to which I know and trust my selfhood—and am willing to make it available and vulnerable in the service of learning.
(Parker Palmer, The Heart of a Teacher)
