Many have argued with me that ambition is not the problem. Women are not less ambitious than men, they insist, but more enlightened with different and more meaningful goals. I do not dismiss or dispute this argument. There is far more to life than climbing a career ladder, including raising children, seeking personal fulfillment, contributing to society, and improving the lives of others. And there are many people who are deeply committed to their jobs but do not - and should not have to - aspire to run their organizations. Leadership roles are not the only way to have profound impact.
