in thread Taking care of your tools

Sharpening a saw by hand is a difficult, slow, and risk-prone activity. If you mis-align the teeth, you may end up with a duller saw than when you started. If you apply force in the wrong place, you may break the blade altogether.

Just to stretch the metaphor, I wonder what sort of activity might be comparable to "breaking the blade". Probably the closest thing in my life is burn-out from a rotten job environment. Had me seriously considering an occupation change.
