15.4 Amanda Horton-Mastin, CEO

Do you believe your own story? Viv Groskop talks to Amanda Horton-Mastin, formerly senior director at Comic Relief and current CEO of Semble, which connects companies and communities to drive positive change. They explore how conviction can be contagious, whether you are fundraising or networking. They talk sickening nerves, and the power of pretending everything is fine. They talk over-compensating for having very fluffy hair - and what losing at tennis can teach you about winning at life. You can find out more about Amanda at Semble.org Viv's book, Lift As You Climb is out now. @vivgroskop
