Lol, I get what you mean. But actually, it's good to know about the Stock Market and such, but you don't have to. By purchasing one of them, you initially own part of the company.
For example: I plan on buying the Polo Ralph Lauren for my sister as a Birthday Gift. By doing so, that means that she owns one share of the company. If the company/industry makes money, so do you
My mum thinks that this is an awesome idea, and actually wants me to go for it, but choose wisely about the one that I want. I only know a bit about this because during my Economics/Government class last year, we had a Game/Test where the teacher had created a pretend "Stock Market Simulation."
I say go for it if you can. Haha I think I am ^.^
