     It may well be true that successful entrepreneurs possess perseverance and leadership skills, of course.  What is less obvious - and much less boring - is what the speaker neglected to mention:  that those traits are likely to be the characteristics of extremely unsuccessful people, too.  "Think about it," Denrell observed afterwards, "Incurring large losses requires both persistence ... and the ability to persuade others to pour their money down the drain." ... It seems likely that the very successful and the very unsuccessful might actually have rather similar personalities.  The only indisputable difference between the two is the the very unsuccessful are much, much less frequently interviewed by management scholars who are studying the causes of success.
