I hope that you will keep the door open to teaching. We need teachers that care about what they’re teaching their students and aren’t just there for the paycheck.
I was dismayed when I started my college career at 34–the classes were mostly lectures with very little debate or exchange of ideas and viewpoints. Those open discussions expand an education beyond the confines of a textbook. In the few classes I had where debates were allowed, i found it thought-provoking for both sides.
