It’s important to put the money aside to pay your bills as soon as you get paid.  That way you will be sure to have enough money to pay them.  Don’t go out and buy things, not even groceries until you’ve put the money aside for your bills.  Most of your day to day expenses are likely to have some flexibility in them, you can limit how much you spend on coffee a day or buy a less expensive cut of meat, but the power company wants all their money.
