Financial talk

I am 14 years old, but I am responsible. I know many of you will say that I am too young to have a credit or debit card but don't post those answers. Only post if you have information that could be helpful to me.(statistics, other info, etc.) I also wouldn't have very high expenses, I would use it to pay a membership fee of $5 a month on a game I play, ocasionally buy things, but I know how to make sure that I have enough money at the end of the month. I also have ways of making money around my house, so I will be able to buy things with a way to pay back the credit. So, if you have anything helpful to say, please post!
