Keeping your credit in good standing means paying your bills in a timely manner. If you are consistently late in paying, it means not only do you have to pay late fees but it knocks points off your credit rating. Keeping your credit score high is important so that when you do decide to approach a financial lending institution for a loan, you stand a better chance of getting it.
Occasionally, due to illness or cutbacks at work, you may not be able to pay a bill as you'd want. In fact, you may even risk losing services if it's not paid soon. It's best to never get in that position, and to have a little savings so that you can pay out of that. However, if you haven't saved anything, you're probably going to be looking at getting a payday loan to pay a bill. Don't use these for frivolous reasons. Use them wisely and pay them back on time. Only get a loan for the minimum amount you need to get you over the hump.
