Boston Globe has an article by Scott Kirsner:
Pure entrepreneurs are loopy and obsessed. They have a vision of the future, and while others are casting their lines into the water to see what will bite, pure entrepreneurs are jumping over the gunwales and swimming after the white whale.
Pure entrepreneurship, by my definition, is often driven by a belief that a major shift is coming — and thus it’s hard to find customers who already understand that they need the product a pure entrepreneur is developing.
Pure entrepreneurship is often a solo enterprise, funded by credit cards, consulting projects, and second mortgages. It sparks revolutions and spawns big companies.
