For what it's worth, if you're a HNer, I'll tell you something Ramit Sethi says often which would have been useful to internalize, oh, five years earlier: it is very hard to cut expenditures in such a meaningful fashion that your financial situation qualitatively changes. (There's only a few big wins there, and lattes or "stop buying books" do not qualify.) By comparison, the amount of impact you can have by moving your salary up is quite substantial indeed, particularly because there's just a crazy dynamic range in our industry and, well, most of us by default do not make choices which tend to land us on the top tiers of that range.
Seriously: I get people who email me on an almost weekly basis saying they got $5k ~ $15k a year just by asking for a raise. You know how many trips to the library it takes to move your financial situation by that much? You won't accomplish it in your lifetime. And that's between a few hours of work or, literally in some cases, minutes.
