How confident are you that your example isn't just survivorship bias?
I know people who failed and got fired. I know people who failed and were forced to resign. Where does your advice fit in the real world?
The fact that there's some sample of "failed and fired" AND "failed and not fired" - even if this was 80/20, one still has to conclude that there's more than just failure at play. Inconclusive evidence to say it's only failure involved..
My experience hasn't been 80/20, it's been more 10/90. My whole company has people failing and founding around the place, I've only seen two people fired: 1 who blamed anyone else but himself, and another who never asked for help and wanted to save face at any opportunity.
Failures are a part of life, if you are at a company that doesn't acknowledge that I suggest perhaps finding someplace else for your own good
OP is the one claiming monopoly on the truth.
"everything sucks and burn those who disagree"
People who get fired are the ones who never learn, and have a shitty attitude about failure.
I know which camp I'd rather be in.
