You fail, that's why you pivot.
Hence the saying.
"Fail fast and pivot"
Pivoting just means you've taken some industry knowledge from your failed attempt at a product, and you are applying it to a new product or market fit by pivoting on your original idea. (at least in the context of start-ups / product development)
There's no pivoting without failure.
Also:
> Trump’s innovation is to have mined a deeper vein of cynicism, exhausting the weary tropes of polite political discourse. He is the ultimate pivoter, aimlessly following his own impulses as his administration is mired in daily absurdities.
WTF? Trump is the ultimate pivoter? Are you serious? This article is just ridiculous.
Someone needs to learn the definition of pivot.
