Episode Summary: You think the latte is $6. Wrong. You think the new car is $35,000. Wrong again. In this episode, we blow the lid off one of the most underrated concepts in personal finance — opportunity cost — and explain why your brain is hardwired to ignore it. From the psychology of "mental accounting" to the sneaky way our brains use "loss aversion" against us, this episode will change the way you see every financial decision you make. Fair warning: you will never look at a gym membership the same way again.
