Owning a credit card is a must nowadays. In fact, a lot of establishments like hotels or airlines guarantee your reservation only if you will be able to present a credit card. Using it is so much fun, too. You get to buy what you need and just pay for it when the billing statement arrives. That's the key to enjoying your credit card. You should never think that it's money because it's not. You should always have money to pay for it because if you don't the interests will eat you up and you'll have a bad credit rating.
