I do not know any successful entrepreneurs that project vulnerability nor self-doubt. For a VC's that's a big no no. So you have made me curious and this is a sincere question.
I dont actually know of any off the top of my head, which is the point of my post. Successful, self doubting entrepreneurs seem rare, successful high arrogance researchers seem rare. I can think of a few executives that seem like decent people, but I cant think if anyone that doesnt act like they know all the answers
