Do you have the confidence to fail? Viv Groskop talks to Jan Ravens, the actress and impressionist. Jan (or is it Liz Truss?) talks about exploring the space between vulnerability and control. She recalls the way mental illness (and the stigma around it) shaped her family life, and reveals how working with others gave her back a sense of control after the strange end of her first marriage. She (or is it Theresa May?) talks the power of the double act, the horror of writing - and the vital importance of doing things that scare you.
