That's a crock of ****, its one of the least stressful jobs you can get. I have no problem standing in front of a class talking, I can explain things well if I'm interested in it, and I can sit down and do paperwork for hours on end without getting bore in the slightest. Teaching is easy, face it. You want a stressful job be a solicitor or barrister. They work
constantly weekends, 7am - 11pm, no holidays, you get the picture. None of this 'lets get paid in August for absolutely nothing' business. Many lawyers resort to cocaine and heroin, they can afford it. If you told me that many of them died of heart atatcks early I might actually believe you.
No offense to your parents but any organised teacher can severly limit their work load by using more effecient teaching techniques. My dad is brilliant at this, he never works at home. He doesn't lesson plan, care to explain why you need to? He cuts out 60% of the syllabus, sure you get no choice of question in the exam but you're still guarenteed to do the 2/5 questions required, and you know them so well that no choice is required. I know in some subjects you can't do that type of thing, like say...maths. But where did I say I want to be a maths teacher?
Basically you can take your generalisation statistics and stick 'em where the sun done shine missy, because it doesn't apply here.
