Today in Southern California, I join hundreds of successful, influential, and prominent female leaders for FORTUNE’s Most Powerful Women Summit. Among those attending include Arianna Huffington, Billie Jean King, Sheryl Sandberg, Glenn Close, and Somaly Mam. We are also screening Miss Representation as part of the week’s programming.

I’m in awe of the collection of talent participating here – it’s a prime example of the power of women supporting one another. The FORTUNE summit itself is co-chaired by three amazing women – Pattie Sellers, Nina Easton and Stephanie Mehta – who have partnered to bring together successful people from all walks of life. Pattie was also instrumental in connecting us, during the filming of Miss Representation, with writer Jessica Shambora (now at Facebook) for the piece below, which compliments the themes of the final documentary.

Mentoring really is a “two-way” street and it’s inspiring to see in action the impact that brilliant women can have on one another. Check it out!
