I'd suggest that your idea of the "normal" professional isn't quite accurate. I worked at a fortune 500 for a few years. Most people put in 35-40 hours a week. Many of them were impossible to get a hold of during vacation. I'd also suggest that teaching is vastly different than coding - for at least half of the day.
My wife worked for a school that was an outlier - I admitted that (see my original comment). I can vouch for the fact that her average work week was 60 hours (for what that's worth). Roughly 30 of those were in front of students if I remember right. It's certainly easier when you aren't a new teacher, but good teachers constantly change their lessons and approaches creating additional prep work.
I've met very few good teachers who weren't putting just as much time into their jobs as everyone here is putting into their startups. Passion is passion.
