I think it's a balancing act between obsessive persistence and failing fast with a bunch of luck thrown in. For every Walt Disney and Colonel Sanders there are probably thousands of people toiling away in their workshops for years on a product that will never see the light of day. And how many budding entrepreneurs are on the cusp of amazing products only to be side tracked by life's other demands (finances, family, etc)? Throw in the herd mentality of the VCs/Funding Sources and it's a wonder any worthwhile company actually gets off the ground and thrives in today's market.
