Say you're knitting a scarf.
Say this scarf has a big fat cable running through it. Say this requires use of a stitch counter so you know when to cable. Say you're not entirely joyous about the product, but you're continuing just because it's something to do.
Now, say you lose your stitch counter. It mysteriously vanishes. You can't find it anywhere. Now you can no longer comfortably cable without marking your progress on a piece of paper or some other such bother.
Lesson: When your stitch counter vanishes and you can no longer easily cable, frog the darn thing (which was turning out fairly ugly anyway) and make stripes instead.
Somewhere a deep life lesson is buried in there. Something highly metaphorical. But I'm too cross-eyed from 1x1 ribbing to figure it out.
