What kind of jerk would YOU be?
In Zero to One, Paul Thiel claims that people with outlier personalities -- jerks, to you and me -- are the ones to become entrepreneurs. Really?
Consider the abrasive Steve Jobs, the ego-inflated Larry Ellison, and Google's "I don't want to grow up" pair, Brin and Page.
Maybe. But if at age 25 YOU got lucky and experienced tremendous success based on something you'd done, don't you think you'd end up indulging your childish side? Pop stars do it. Actors who find early success do it. Even George Armstrong Custer, a general at 23, did it (and see where it got him!).
So, it might be that a personality that (over)exercises the id leads to entrepreneurial success. Then again, it could be the other way around.
