There's an undeniable and oft-proven statistic out there: The more diverse an organization, the better it works. Period.
Specifically, more women in leadership means more profitability.
In "Women Make Great Leaders: Real World Lessons to Accelerate Your Climb", you can read about great women who tell their stories in industry and as wildly successful entrepreneurs. All have much in common: bravery, the willingness to step out of line, a strong belief in themselves, great relationship building skills, and much more.
These are women who have beaten the odds. Early on, they heard the whispers..the inner-call to leadership. They answered, and continue to answer it, with fierce passion and the courage, boldness and resilience required to rise to the next level.
These women are doers and risk takers. Many become devoted wives, partners and mothers while still building careers and influence. They all remain true to their work as leaders in the world, carrying it out with the grace, diplomacy and fortitude it requires.
