I suspect this is a key insight. There is a colloquialism for a company of people all trying to be 'the boss' called "Too many Chiefs, not enough Indians" (in reference to the tribal organization of Native American tribes, where in fact there was exactly one Chief who was the final arbiter) but another spin on this is "Too many Medicine men, not enough Indians."

The "fantasy" life of a startup founder is that they see things others don't (vision) and lead people who make those visions real (workers). Except you can't really lead someone with a vision if you don't know yourself how to make that vision real.

The challenges of startups are that you have to be able to "do it all" in order to know what "doing it" actually entails, then you can bring people in who can do a part of it (that you were previously doing) and know if they are doing it well or not. Folks who are visionary in their thinking but can't break that down into actionable steps toward that vision, and then break those steps into problem assignments, aren't really going to be an asset for your startup until you already have a product and a revenue stream.

Even then, there is nothing more irritating to folks than a clueless visionary. Someone who says something like "The underlying problem is energy dependence, so our goal should be to provide an unlimited energy source to break that dependence, let's get some smart people working on that!" Accurate vision, but ultimately clueless, they just slow people down who have to explain the 2nd law of thermodynamics to them (if they are patient enough).
