So, I have always had questions about what Credit really is, and how to make the best of it, and I have a few questions that I'd like to ask: 1. If you where to use a credit card to let's say, pay your payments/buy everyday items, and you always pay it off that day or at most a week later, would that improve your credit more then just buying and selling with money or debit? 2. How can you improve your credit score other then a credit card and paying payments on time? 3. What good is having a high credit score? 4. What is your credit score when you become 18? I mean, is their a standard everyone starts with?
