There is a school of thought that entrepreneurs are either born or can be 'taught'; either way, entrepreneurs tend to exhibit certain character traits - passion, imagination, seeking to direct their own lives and not be dictated to by others as to how they should work, seeing the extraordinary in the ordinary...
All traits that are also common amongst poets - poets who, over the centuries, have challenged our views of the world in ways that entrepreneurs do today and in doing so inspired us, changed the way we act and ultimately changed the way the world works.
Surely then there's a lot for today's entrepreneurs to gain from looking to this richer source of guidance, instruction, understanding and inspiration which just doesn't seem to be happening anywhere.
As an (initially) closing thought - consider this passage from William Blake's 'Jerusalem', first written in 1803:
"I must Create a System, or be enslav'd by another Mans;
I will not Reason and Compare; my business is to Create."
