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).
