I would say the best realization of this article is that entrepreneur is a state of mind. A willingness to create from nothing in the face of extreem adversity.

I agree with this. I came across the following definition of an entrepreneur, which I also really liked: "[the] definition of an entrepreneur is someone who makes things happen despite not controlling the resources necessary to achieve them."
