I wrote down everything I spent in a month, many years ago. At the end of thirty days, I considered the spending categories and shrugged. I've never maintained a budget, or wanted to. I think it takes dedication and perhaps the soul of an accountant to stick with one, though it's much easier now with the appropriate software.
Oddly, I regularly record my food intake in a nutrition program, finding satisfaction in hitting my macros and seeing how close I come to meeting micronutrient needs.
