Why are we, as a community, having these "epiphanies" about how to start and run a successful business? The functions and skill-set may have changed, but the core principles that drive an entrepreneurial undertaking have not. For over a hundred years.
Sometimes it seems like we believe that we are paving new ground, when all it is is that we never bother to learn from those who have traveled this road before.
A "hustler", as the article defines, should be the function of everyone in a startup, even us "hackers" (if we can come down from the pedestal).
