Anthony Tjan, HBR:
One of our most striking findings was that of the entrepreneurs we surveyed who had a successful exit (that is, an IPO or sale to another firm), about 70% did NOT start with a business plan.
Instead, their business journeys originated in a different place, a place we call the Heart. They were conceived not with a document but with a feeling and doing for an authentic vision. Clarity of purpose and passion ruled the day with less time spent writing about an idea and more time spent just doing it.
It doesn’t take much though to see why this makes so much sense.
