In her new book, Uncharted, Margaret Heffernan predicts a coronavirus epidemic - and then had to cancel her book launch when it struck. Luckily, she's used to change. She went from being a BBC documentary maker to being a tech entrepreneur. Her TED talks have been watched by more than 12 million people. In this podcast, she talks about the importance of friendship at work, how to make boring work interesting and how to have a good pandemic.
