What problem or situation did TV / movies make you think would be common, but when you grew up you found out it wasn't?

I would say money, in most tv shows and movies it seems as if money was so easy to get and saving it was easy and still as a kid I know this, money is not easy to keep or get. To get the money you have to work for it by a job, or by walking a dog (which is not easy when your skinny and no muscle to hold an excited dog on a leash) but, then you have to learn to save and also to learn to know whats more important things you want vs. necessities. In movies, it's like they get money out of the clear blue sky? It hard to get money or things you want without working hard for it, tv shows and movies make it seems easy for sure.
