Question by Marissa: Will a couple screwups with my credit early in my life (age 18) weigh me down in the long run?
Here's the deal.

I had just turned 18 and sent in at least 7 applications for credit cards before knowing it was bad for credit.

One time I went over my credit limit on one credit card and paid the fee and never had it happen again. (this was my 3rd month of owning the card).

I had 3 credit cards from major companies to begin with and got rid of one after
