In my experience, it's the same with every framework, entrepreneurial or not.
There
are people out there who just take action. Like this guy I worked with who just decided to start a company and spent two years working on it like crazy. He ended up shutting it down, and arguably he did make a bunch of mistakes. He also made some side cash along the way, ~100k, and met a ton of people including myself, so in the end it was not even wasted: he is now working 9-5, but is making a lot more money because of that experience.
However, those guys are rare. Other than that, the next category are
smart people like myself. Those folks often have a M.Sc. or a Ph.D. in something quantitative, or in something requiring enormous attention to detail. If you are a software developer, engineer, accountant, analyst, physicist, researcher of any variety, lawyer or paralegal, even marketing specialist, you fall into this category. Then you will
love frameworks because they give the world certainty. Suddenly you feel like you know, but you don't. If you are one of us smarties, the solution is to
forget about CENTS and any other frameworks. Getting a mentor instead might be a good idea. Otherwise you might be under an illusion that you are making progress, while you won't be.
It's also very hard to put those idioms into context without, or even with experience. E.g. I knew a guy who kept saying, how easy it is to raise money in the Silicon Valley, that if only you have a big idea that can scale, funding is not a problem. Surely, it is relatively easy, but that is not a productive mindset when you have a startup. It was "easy", until the investors suddenly stopped giving money because they wanted progress. Suddenly they realized that a grand vision was not sufficient if the team cannot execute.
Then I know this lady, also very smart, who is struggling to make the ends meet. Literally struggling to survive. She will tell me all those theories, as to why her "real rate" is $250/hour. You know, why people "should" outsource to her because their time is more expensive, so it should make logical sense to give her the kind of work she has in mind, at the rates she has in mind. Great, except she can't make $15/hour despite her incredible analytical skills, top 1% of the population by any standard. She just has some abstract theory explaining why she is right, but there isn't a market for her skills at the rates she has in mind, or she has no way of accessing that market. Now she has 17 contacts who say they will hire her "some day", once they can afford it! Most of those contacts are early-stage entrepreneurs. The framework (how much their time is worth) doesn't even apply here, because they simply do not have $250/hour or even $50/hour to spare at the moment, let alone that her theoretical analysis is not very useful for an early-stage startup. Same story: a person stubbornly clinging to a framework instead of engaging with reality.
To elaborate on the last example, there is a barrier to entry to consulting at $250/hour, which is not just skills, but connections and experience — experience knowing how to talk people into paying you $250/hour, and then how to meet their expectations. She doesn't see that without this communication her "objective" value does not exist. Similarly, there are countless other obstacles that can invalidate a business plan. We simply cannot know in advance if something will scale or not, if something will create value or not, etc. The framework is there so that once you have 10 failures, you can look at them and create an 11-th success. It cannot be used to manufacture success at 1st attempt because real life experience is needed to interpret the framework, and to keep interpreting it day-to-day.
