Seven-minute safety net for entrepreneurs

"All you need in this life is ignorance and confidence; then success is sure."

    Mark Twain

I sometimes wonder how far Mark Twain could jam his tongue into his cheek. 

Launching a business from a position of ignorance will not assure success.  That's obvious.  Entrepreneurs clearly have confidence.  It's part of what I call Moxie.  But they absolutely must avoid ignorance.  Duh.

Here's what I like to think Twain might have said, if he had been a business consultant, instead of one of the greatest humorists and social commentators of all time.
