Writers Bloc presents a conversation with Sheryl Sandberg, Chief Operating Officer of Facebook, one of the most powerful women in business anywhere in the world, and Michael Lynton of Sony Corporation of America. She talks about the obstacles that women in business with ambition and talent face every day -- children, marriage, and family. It's all made more complicated because it involves embracing challenge, and going toward goals. Sandberg also argues that a new women's movement is afoot. Her new book is "Lean In: Women, Work, and the Will To Lead". This conversation was recorded at the Writer's Guild Theater in Beverly Hills on March 18.
