I try to pay all of the bills as early in the month as possible. I only have my Social Security to live on, and so it only comes once a month. After everything is paid, then I know it is safe to buy other things that I need. A person never knows what unexpected expenses might come along during the month, like issues with the vehicle and such things as that. If I know that all of the necessary bills are paid, then what ever is left is what I can use for other things, hopefully saving a little to have in case of emergencies.
