This sentence tripped me up. I vividly remember some of the more boring classes where you end up staring at the clock, for some subjects I actually tried to put in the least effort possible to achieve 80%. I wish I had those years back to do follow something I really enjoyed doing.
Does that make sense to everyone but me? Or am I just being silly/obnoxious for complaining about (what I think is) an editing error in an article with an actual point?
Or is meant like "he never understood that he never got a high school degree"? I'm not a native speaker of English, and the missing "that" in the linked-to article makes this interpretation feel unlikely to me.
Confusing.
