I once came across a “Crap” ink stamp online and had to laugh.
Truthfully, it would be a really good thing to have around. A lot of wasted time, energy, resources and money could be saved if people were willing to call a doomed project what it is…crap. It takes courage to halt a project in the middle, and even more so near the end. But part of being productive is recognizing when an effort is not steering you toward the right result.
The best solution is to stop, call it like it is, and redirect all efforts.
