While simple on it’s surface, this seems simple but it’s an excellent way to mind your money. I too was one of those that would get to Monday or Tuesday and wonder where all of my money had gone… When you take into account every soda you buy, every candy bar, every meal eaten out, every stupid little thing off the rack by the counter, it all starts to add up. I was writing mine on a piece of paper that I would keep in my wallet, but using excel is an awesome idea, so thank you.
