Please allow me to preface with this: I figure your intent is not to demean the tasks of other professions, and none of what I'm saying is rhetorical.
That said, why not take the job of caring for the elderly relatives? Use it as a way to buy yourself some time while you become a specialist?
(I know a couple of people who have worked as certified nursing assistants for about ten years, among other things, scooping poop. They like excrement about as much as, I presume, most other people in existence; for them, it's a fact of life, though, and they're able to support their family well enough.)
Understanding by the greatest possible number of people should be the goal here, in my opinion.
GOAWAY makes plenty sense when compared to GTFO, assuming that not everyone who learns of it intentionally is well-versed in that of which GTFO is a relatively smaller part. Grandma wouldn't necessarily get GTFO (right away, anyway) but she would likely pick up GOAWAY in a snap.
Of course, the above assumes a section of people who are fluent (enough?) in English to grok the spec.
