Artificial milestones to proceeding with a plan or taking an action, you're describing a literal milestone of fitting everything in your car due to a practical need.

I was down to the point of it all fitting in the boot of a sedan but had no rhyme or reason to it at all, I was just acting out against a bunch of other stuff because I figured once I was done, I'd be "ready"

_that_ is an artificial milestone.
