Sheryl Sandberg is a remarkable person.  Alongside leading a $500 billion business, with 24,000 employees and 2 billion monthly active users, she has mobilised millions of women around the world to achieve their ambitions and fight for a more gender equal society.  Sheryl’s own story of resilience came to light following the sudden death of her husband in 2015, and her subsequent journey to recover, rebound and flourish again. Sheryl is Chief Operating Officer at Facebook, Founder of LeanIn.Org and OptionB.Org and I caught up with her to learn about resilience.
