When teaching middle school English, I had six preps for the week: 8th grade English, expedition (interdisciplinary) block, crew, writing intensive, and reading lab. The sixth prep was for myself. I had to prepare to be my best self in the classroom each day. Some teachers have equanimity easily accessible; some of us are, shall we say, a little rougher around the edges. I needed to do the extra work to scan my body, breathe deeply, and maintain perspective.
