Interesting piece in Inc. Magazine citing the work of HBS professor Howard Stevenson in the late 1970s.
Stevenson captured the essence of entrepreneurship in 25 words:
Entrepreneurship is the pursuit of opportunity without regard to resources currently controlled.1
And this, says Inc's Editor-in-Chief and article author, Eric Schurenberg, "is what makes entrepreneurship so friggin' hard. And so friggin' necessary."
