Can confirm this. I taught for a bit (coding bootcamp, 1 year). I was super excited my first 3 months (it normalized after that) and during the whole year I had a lot of empathy in the sense that I felt their pain. It’s easy to feel someone’s pain when you yourself felt it a great deal as well back then.

I was at my best during those first months. Experience and empathy all help but I could notice how being only slightly enthusiastic was hindering my performance.
