Could not recommend teaching more. Good on you! 
Personally i'm conflicted because what I want to study (investment banking) has a better income outlook, but really, quote famous chinese teacher:
'Everyone wants great teachers, but how can there exist good teachers if students don't learn it?'
After experiencing 4 years of a variety of teachers at a private school, i'd confidently say that the best teachers can influence your study score +- 5 towards the high end. It's that big.
All the best man, hope to see you at a prestigious private school/top public school soon (or maybe you might be the kind who'd rather significantly influence the schools where not everyone has such privileges).
thanks man, that was actually really inspiring! I agree, having bad/good teachers makes a huge difference, not just in how you learn the content but in the support they offer you throughout the hard times of VCE (and schooling in general)
I think while teaching has a typically lower income, because of the (relatively) good hours, you can work outside of class, writing textbooks/exams, tutoring or even working a side hustle- one teacher at my school owns a very successful picture framing company on the side
To prove that teachers can make money, my physics teacher somehow owns several sports cars, a few beachhouses and travels internationally all the time (pretty much has enough money and time as he needs to just enjoy his life). This is because he writes textbooks, drops into monash for the occasional lecture and also runs the neap physics lectures. Considering the hours he works (would rarely see him at school past 3:10, marks all sacs in lunchtimes and spares), that is crazy good money. That being said, he has been teaching for 40 odd years and you can't just write textbooks from day 1, but still proves that teachers can make money if thats what they want to do
I think in writing all this out I've just convinced myself to be a teacher! ahaha
