So I agree about the 'cadence' bit.
But this:
" Imagine if you could have skipped all those English classes back then. Guess what? You would be learning it all right now!"
No, no way.
It's a total misunderstanding of education to contemplate this.
Education is not 'some facts and things you learn that you may use later'.
Education at HS level is much more fundamental than that, particularly English.
It's about communicating, developing ideas, writing. Not only is it essential, it takes quite a lot of time and effort, and it's hard to just 'pick up'.
I have an Angel investor friend who just set up his own basic website (simple is fine) and wrote his own little intro copy. It's atrocious. Basically, in four sentences in writing, he reveals his own lack of education to anyone who cares to read. I mean - it's not 'that that bad' - but it really is sub professional and embarrassing. He's otherwise very smart, very educated, but it turns out he can't string together a few tightly coherent sentences to make a point.
There's no 'going back'. Both of should have paid more attention in school.
I do agree with he cadence, I think that school days should be shorter, and there should be more music and sports, shop class and longer term projects.
