While part of me cries “unfair” more than I would like it to, this is Johns list, and he gets to recommend as he chooses. What actually concerns me — and I hope you as well — is that in his canon of leadership books there are no womens voices, at least not in the top 11 that he relies on and that inspire him to greatness. Johns picks, however, are not an anomaly among men, or even really among women. When I recently asked a group of successful professional women to list their favorite books about entrepreneurship, the list skewed largely male. Not too long ago, my list did too. And that is a problem. Unless of course, we believe women have nothing to offer as leaders.
