Sorry guys, but I ain't buying what you're selling.
My mom was a (career) teacher in the public school system (Canada). Loved her job. 30+ years doing it.
Teach the same grade/subject for several years, and you are basically using the same lesson plans. This 75 hours a week is malarky I say! (Are you adding in your commute to/from school and your lunch break?)
Plus, with a private school you prolly have a lot lower student : teacher ratio.
What was your average class size? Grading papers all weekend every weekend.:hmm3grin2orange::hmm3grin2orange::hmm3grin2orange:
Anyway, if you think your indoor, climate-controlled desk job was brutal, then you got another thing coming, and the honeymoon is gonna be over before you know it!
