I have two sisters and brother that were teachers. The sisters married professionals, one married a CPA who has an audit firm, the second, married a pipeline engineer. They both use their summers to recharge
and reformulate class material and educate themselves to be current. They loved teaching and it showed with their students. Oh, they worked for piss poor school districts that the most they made based on their years of service was $36,000. They used books that were out of print, chalk boards instead of over heads,
and took very little crap from students. They told their students that they had better pay attention because
it was going to be fast and furious....and the kids loved the challenge.
The brother made a fortune in holding summer camps for football, basketball and baseball. It was his choosing. He called it his retirement plan. I guess it worked. He's retired to holding full time sports camps.
