Thanks for this great post. After speaking with some really successful entrepreneurs, I noticed they are extremely stubborn (in a good way) even after failing several times. The odds are stacked against them but they still allow themselves several years to find a semblance of success which they can develop further. I appreciate your article. I am working on similar topics for my book Disruptors so posts like this help.
I just bought the book! Working on something very similar (www.Disruptorsbook.com) but we both have featured different entrepreneurs and different angles. Would love to talk sometime!
