I, too, was teacher and I found that for most long term teachers it is not a difficult job. Those that try to perform their duties to a satisfactory level soon burn out and quit.
I did and I assume you did too.

I always try to do a good job wherever I work.
Most of my teachers that I had when I was a student were good, but that was decades ago and the work ethic hadn't eroded away yet.

I did have one remarkably lazy professor.
Someone asked him a question in a technology class. He refused to give an answer to the class. He said, “That's in the book.”
He didn't lecture, he would only read out of the book.
One day a student said, “We could sit up there and do that, read out of the book.”
I imagine they have more teachers like him now-days in the public schools....
