An epiphany hit me this morning while I was in the shower. I recall groaning at how ridiculous the whole thing was but as much as I try to recall the exact epiphany (which had a really nice ring to it), I can't. A "doesn't sound as good as the original" version is:
Epiphanies only hit you when you're unable to do much about it, after which your mind carelessly shoves it aside to tell you to concentrate on what you're doing instead. It then forgets to save it, nor will you be able to 'auto-recover' it from the depths of your brain. Or even if you do, it's just fragments of the real thing and doesn't seem as solid anymore.
