Have you stepped into your greatness? Viv Groskop talks to Vanessa Sanyauke, founder and CEO of Girls Talk London and expert in diversity, inclusion and sustainability in business. Vanessa celebrates uncertainty, curiosity - and never listening to your parents. She calls on us to move from being allies to advocates for marginalised communities - and reveals how important male allies have been to her journey. Oh, and she shares what Oprah Winfrey told her about how to look great in photos...
