These are *exactly* my thoughts James. It's like you took a peek into my behind-the-scenes thinking and put it into words.
I also think entrepreneurship and art are not separate games, but working parts within a larger system where the skills and methods of both are vital to succeed.
The art side could be seen to be about craftmanship, taste, originality, novelty, empathy... in short, creating good work, work that matters.
And entrepreneurship encompasses things like building social networks, managing capital in all its forms, creating infrastructures... effectively: reaching people and making them care.
The analogy was out of the scope of this article, but I'm aiming to eventually write something coherent about it.
So far I'm in a similar situation: I have the hunch and maybe a couple of examples to give it some strength, but not much more. I heard, for example, that da Vinci lost the Sistine Chapel gig due to what we might call "poor networking" (and not lack of artistic prowess), and well, then there' s van Gogh who only sold one painting during his lifetime, but became famous thanks to his sister-in-law, who worked as an art dealer, translated Vincent's letters to his brother, and essentially build his fame through efforts that were entrepreneurial in nature.
This is fascinating stuff. If you happen to know about a book or something that explores this analogy, let me know!
