You asked me why I didn't learn anything from those experiences and I explained. I'm not claiming to have the answers on how schools should be run or demanding my preferences implemented. I'm explaining my own perspective and acknowledging that the common view on these policies has changed since I was impacted by them. Personal viewpoints and anecdotes are still welcome on HN last I checked.
And if you knew one of the specific teachers I was actually referring to, and what he did and why he got fired, perhaps you'd understand why it's difficult to consider him "decent". As a result, I don't assume all teachers mean well by default. But that particular anecdote is not one for HN, and this conversation is boring me as much as that poem.
I do hope you found some help for your ADHD though. There are lots of medicines and lifestyle changes that make it possible to function even in extremely demanding roles, though getting it all nailed down is tough.
