Spend some time this weekend gathering all of your bills. Now, get out a calendar and write when each is due onto your calendar.
Look at pay stubs. How much money is coming in? When does it go into your account? Figure out how much money you have.
Now, divide the bills into pay periods. If you have too many in one pay period, see if you can get the due dates changed. Call the companies.
When you do these things, you have just made wonderful progress in getting your bill paying on a current footing!
