"That is to say that great general business ideas and concepts don’t stay private. Anyone who believes they’ve found a novel angle of analysis is out there sharing it in books, podcasts, blogs, and twitter." Indeed, and that's why you need to stay on the edge. Applies to science as well. "So realize Jeff’s wisdom: Nobody will know your business better than you do, if you’re attempting anything novel. Accept that general business advice can bring another perspective, but you’ll ultimately have to develop your own." However, I am not really sure whether confidence alone matters. Maybe so with experienced entrepreneurs, but I'd argue that you still need an incubator with younger engineers (students) seeking an entrepreneaul career. Scientists are particularly poor at this, by hypothesis.
