my degrees are in engineering however i went for that when i was very poor and having a decent salary was more than i could wish for. but now i realize that working for a salary is a waste of potential. also when making purchasing decisions i want to make sure i don't get schemed. when somebody explained to me what market segmentation was ( how you manufacture an inferior product at an increased self-cost to make more profits ) that has allowed me to see a lot of things that i was previously blind to. and still i missed some. for example i went for naturally aspirated V8 instead of 6 Turbo because V8 had more power according to manufacturer specs. but it turned out 6 Turbo was under rated for the purposes of market segmentation and actually 6 Turbo had more power while costing less and having specs for MUCH lower power than V8. it still hurts to think that i paid extra 10 grand for less power all because i was not as business savvy as i should have been. all i had to do was figure out which engine is better. i am an engineer and i failed. ironically if i was a businessman i would have gotten it right. i simply didn't expect the manufacturer to deliberately lie on the specs to UNDER rate their own engine. so anyway market segmentation is the only thing i know about business. and i want to know EVERYTHING about it. at the same time i don't want to go to college again because i believe that's a waste of time and money. how should i educate myself on the subject ?
