A list of your income and expenses, no matter how complete, is not a spending plan, but is the information you need to create a spending plan. And, a paycheck_by_paycheck spending plan will help ensure the success of, or at least help prevent the failure of your budget.
Just being aware of how much you are spending versus how much you are saving can have a huge impact on your financial picture. For example, there are numerous restaurants in cities all across the nation that have kids eat free specials. You can find a number of these online and you may also want to get into the habit of checking local restaurants to find out which ones offer specials. For those with children, this can mean the difference between getting to eat out and staying at home so it is definitely worth checking out.
