When I did do that four letter thing, I was a banker. Loan Manager for a small tech company credit union in San Jose was my last yob in the late 90's. Graduated college on the east coast as an Economist, so of course, I do understand the value/purpose/use of money.
I also understand the opposite rule, the borrowing one. The fixed interest in a skyrocketing market one. The I financed my home at 3% fixed over so many years that within 5 of paying, my mortage was already €1000/month less than the cost of renting here.
Also, the "how" of making money without working. Now THAT is a book y'all need to read!
No trust funds, no inheritance, no savings, no slaving my life away at a desk. Just a few phone texts, send a few people to do some work they didn't even know existed, and sit back and collect on the fruits of someone else's labors while I go surf, shoot some hoops, garden, play with my pets, play some chess with my neighbor (who absolutely is loving my phylosophy of life and how NOT to chase the almighty dolla no mo, adapting and adjusting he's made it to only working 2 day weeks, getting paid for 6) or hanging and spending time with my wife or my friends.
I simply took what was done to me as an employee, and started to employ those in need of gainful employment. Send a guy to do a €1000/week garden clean up or house maintenance for some rich folks that you know, make sure your guy's good with €800, you just made €200 for doing nuttin. Have 10-20 guys, you're making a decent living salary, still not doing nuttin.
Not too hard to figure out actually.
I also was extremely lucky to have had the financial knowledge I did, right before the € came into existence. Buy property until you cannot anymore, even tapping out loans, family, friends, etc .... As soon as the € came into existence, it was better than Crypto my erBB bro-brahs!
Now I don't even have the crew anymore, what for? Living off rents is fun, yo!
