How you manage credit cards will determine whether you establish good credit or bad credit. If you pay at least the minimum payment on your credit card bill by the due date each month, you are on your way to establishing good credit. If you miss payments or go over your limit, your credit history will take a hit.
Having a bad credit history is a lot like having a bad GPA. Once it goes down, it’s hard to build back up, but it can be done.
