One reason I was attracted to academia was the variability in schedule; Keeping busy by ever-changing topics, revolving classes throughout the year, and guiding students through novel information.
All of this results in an occupied mind (and I need A LOT of “channels” to occupy my mind).
What ceases to amaze me is the deluge of information and activity that accompanies each term. In the ancient past (last term) the busy builds to a crescendo and we long for the sweet release of the inter-term break… Just to be shot out of the cannon into the next.
