I decided to get more rigorous about my budget. I’d done some estimating before, but thought that in the interests of science I should document things more carefully. So I did something I’ve never done before and am not particularly eager to do again: I carried around a little notebook all month and made careful note of every time I spent money and how much I spent and what I spent it on.

I wanted to make sure I was actually living in my budget since I know how easy it is to spend semi-consciously or to justify “exceptional” expenses. I also wanted to be able to point to some real numbers in case anyone skeptically asks me if I’m really able to live comfortably on $15,000 a year in San Francisco. (According to this article in ’s San Francisco Chronicle, I shouldn’t be able to get by on any less than $27,781.)

So, to enlighten you, to amuse you, or to treat your insomnia, here are my results:
