When it comes to your credit score, are you a rock star? There are lots of numbers in life that really matter. While your social security number and your anniversary date might top the list, your credit score ranks higher in importance than the number of adoring fans or social media likes you have combined. In other words, it’s kind of a big deal. Your score can determine the ease with which you make those big purchases, the amount of interest you have to pay back on loans and even other opportunities. So, if you want to be singing arena rock anthems instead of sad ballads about your financial life, rocking your credit score is a good place to start.
