Of course, as the material points out so clearly, you are who you are and to be someone else will work as well as wearing a small glove on a big hand; not a good fit. However, you can, as I call it, "channel." And what I mean by that is, like the text material points out, emulate a former teacher of yours that you admired for whatever your reason may be. For example, there are two that come to mind for myself: my third-grade homeroom teacher and my 11th grade social studies teacher. They were both very different personalities, but sometimes I can see myself acting like one or the other when I teach; it seems to work out for me. One of the cons (sometimes, anyway) for me as a recent college graduate, and former non-traditional student, is that I tend to find myself identifying with my students rather than with the other educators at my campus.
