Laura Walker, President and CEO of New York Public Radio, Arianna Huffington, chair, president, and editor-in-chief of the Huffington Post Media Group, Herb Scannell, President of BBC Worldwide America, and MaryAnne Gilmartin, CEO at Forest City Ratner Companies, check in on what they learned and what permanent changes might work for them.
