Hello there, future economists! Let's embark on a time-traveling adventure and decode the history of economic thought.

The word "economy" hails from ancient Greece. It combines "oikos" (household) and "nemein" (management and dispensation). Picture the ancient Greeks managing their resources like a super-organized mom managing her kitchen. Today's economics has grown beyond the household but, hey, we all started somewhere, right?

Adam Smith is the Mick Jagger of economics. He strutted onto the scene in 1776 with "Wealth of Nations", belting out new tunes about individual self-interest and market mechanisms. Think of it like this: You don't go to a concert because you love the band (benevolence), but because you love their music and how it makes you feel (self-interest). His metaphor of the "invisible hand" also rocked the stage, symbolizing how individual decisions could lead to organized results without any direct intervention.

While Smith was all for the free market, he wasn't anti-government. He believed in a solid government that ensured the smooth functioning of markets.
