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.
Setting up a budgeting worksheet isn't a hard chore. In fact, if you like using spreadsheets it can actually become quite enjoyable. The beauty of a budgeting worksheet is that you can see all your numbers at a quick glance in an easy to read format. It's instantly editable so changes can be made on the run and will save considerably on white_out. And perhaps the best feature, is that you can always keep a history of your transactions (depending on your hard_drive space).
