Dude! I've been doing the exact same thing... since August 2003. I track every transaction that I make, and divide them into Bills, Food and Fun... but lately I was finding that it wasn't changing my habits at all... and so budgeting is honestly helping me make decisions like 'Oh, I'll save up and buy that thing next month because I've nearly hit the budget target for this month.' Although, if I'm tired or hungry, all of that goes out the window.... so I know I can't let myself get too tired or hungry.

Haha, love that idea! I've actually being thinking about something along similar lines, and I do definitely have the space here... it just becomes a matter of do I want to spend the time on yet another project.
