First of all you need to know how much money you earn, for some people this is easy you look at your Wθ form and there it is, but for seasonal workers, small business people, it gets a little more complicated than that. If you receive income from a lot of different sources for a realistic value of what you actually earn itemize them, put them down on paper. Include all income, now is not the time to be hide money from the IRS you are just fooling yourself, you need to have factual figures here of your true income otherwise you will actually think you're in good financial shape because you know you got this extra income somewhere, but that's not always true.
Second, and more importantly, this method doesn't provide any real guidance on what to do with money as it comes in. You're left to try to figure it out as you go. Mistakes are made...frustration sets it... you give up. That's because your budgeting worksheets are missing the most crucial part of any budget _ the spending plan.
