Do you budget/track income & expenses? If so, how do you do it? →[More:]I'm fiddling around in Excel, drawing up a spreadsheet to track my hours and income. It occurred to me that this would be a good place to keep track of other income, expenses, etc so that I can finally do that budget I've been thinking about for years (duh). What's your approach to this? What works best for you? What hasn't worked?
