Could you benefit from *extreme* financial planning?

I'm not talking about the kind that typical fin-planners or software set you up with (eg. balance your checkbooks, pay your cards off at the end of the month, etc.) - y'know, the common-sense stuff that doesn't really apply.

I'm talking about penny-pinching, lifehack-style tricks to keep things afloat while you work on your long-term situation.
