Understanding Opportunity Cost

Every single choice you make has a hidden cost. It's called opportunity cost,

and it's the next best thing you gave up to do what you're doing right now. Think about it:

you chose to watch this video instead of studying, sleeping, or making money.

That's the trade-off. This is the core of economics: we have unlimited wants but scarce resources

like time and money. We can't have everything. This forces us to choose, and every choice

means sacrificing something else. It’s why countries can't just build infinite hospitals

and schools. So, what did this video just cost you?
