Basically, there are two ways to use your credit card; responsibly or irresponsibly. If used responsibly, your credit card will be the best short-term loan you can find. But if you use it irresponsibly, it will turn into the worst high-interest loan you have ever seen. That being said, the latter is what your credit card company prefers because they generate revenue off of your irresponsibility. However, if you were to use your credit card responsibly, you would be using their money for free. The choice seems like a simple one, but you’d be surprised.
