What I take from this as an entrepreneur is: Have a vision and bring it into the world. The market response, and the financial outcome, are irrelevant.
If you disagree, it's probably because you feel that the ultimate goal of entrepreneurship is wealth. I used to believe this myself, and I can certainly understand the perspective of those who do.
As for the article, this line is pretty telling:
> make a bold statement about the problem (without too many specifics about the solution) and gather email addresses of people who wanted to join the movement
This particular journey seemed a lot more "tell me what to build and how to make money from it" than "here is my vision," and there's already some grandiose idea of a "movement" before even some vague outline of an actual solution/product have been conceived.
There's also a strong whiff of the toxic "fail fast" mentality. Oftentimes, tremendous persistence and radical care are the difference between success and failure. I shudder to think how many fantastic products have died under this type of thinking, when the real issue was some deficiency in execution, positioning, etc.
I say this in part because a year is not much of a sacrifice, at least from the perspective of an entrepreneur, and especially when you have the financial runway to do it. Any sane person would probably disagree, but it's neither the job nor the nature of founders to be sane.
