When my then girlfriend now my wife and I were juniors in HS we signed up
For an elective class called “consumer education and personal finance”. I have no idea why this wasn’t a required class from junior high through high school. We learned about investing, compounding interest, banking, insurance etc. I got more out of that one semester class than 4 years of other subjects combined. When HS graduation day came I searched out that teacher and thanked him for teaching this class. A few years later when I was just starting my business he hired me to do a bunch of work for him. I like to think that class helped seal the deal and convince my girlfriend to marry me!
I still remember a quote that teacher said. He said “rich people stay rich by living like they are broke. Broke people stay broke by living like they are rich”.
