Exactly. People tend to worship personalities all-in just because they are successful. However it might well be the case that they're successful despite their personality issues, instead of "because of" them. When I was reading Peter Thiel's startup notes I kept thinking: He is successful, but it doesn't mean many of his thoughts make much sense or are actually applicable. Maybe he just succeeded despite holding some wrong beliefs. I would hypothesize that some founders succeeded despite being jerks, but most jerks are not successful founders, and most successful founders aren't jerks. In any case, if somebody has excellent ability in performing correct inferences and a healthy dose of self belief as he knows what he's doing and knows he has indeed accumulated more than many others trying the same thing, those can indeed be positive personality traits. However if one goes as far as really to "distort" the reality/self perception, I don't think it can end well at all and might well wreck havoc and can even be classic signs of depression. Objectively evaluating evidence, understanding that human beings are not fundamentally different, genuinely listening to others and immediately acknowledging own folly can only be a plus in all sorts of scenarios.
