Sometimes, I'd venture, that is exactly what makes the fifty first succesful.
There are guidelines to what you should do, and what you shouldn't do, but every case is different. Clearly, there are things that you aren't likely to ever want to do (rm -rf /), but there are plenty of instances in which a company didn't succeed doing x, and then a later company succeeded in doing exactly x. Whether it was due to a difference in the timing, or a difference in the market, or that something else within the company made x work differently for them than their predecessors, who knows.
Admittedly I'm just playing devil's advocate, but I feel like not enough focus is given to learning from these sorts of guides vs just blindly following them as a business plan.
