To serve client better, I have devoted considerable time in my legal career to understand entrepreneurship - (see my recent Entrepreneurship Toolkit post at http://www.dilanchian.com.au/content/view/90/56/. Therefore I value your focus on the critical question of what might be some of the personality traits of entrepreneurs. I would add that in the context of corporate entrepreneurship the research and books (eg "Built to Last") of Jim Collins do suggest that your first and last bullet points don't necessarily apply.
