i'm sorry but how am i a troll, or loving stupid? if you bothered to follow the quotes back to the original post you'll see what he's saying. you don't need to worry about this kind of stuff when you're 14, forget.
At 14 you can work.
If you, like everyone else, have parents that care a bit, you may have a bank account with a few thousand to get you a car. If you have a job, fantastic, you earn some to spend on trivialities.
But, when you get a car, you're going to want a good one, so you spend a lot, and then you look to a house, or renting, a girlfriend, etc.
Its good to at least have the necessary understanding and a few plans about all that.
