Self-esteem is mysterious, fleeting and vital to every decision we make. Sophie Duker, Heidi Regan and Ned Sedgwick are joined by activist and writer Ellen Jones to talk all things imposter syndrome, confidence, self-worth and yoyo tricks. Sophie tackles your inner (non-existent) fraudster, Heidi ponders the mysteries of confidence, Ned shows off his jingle making skills and Steve Ali puts a listener's dilemma into perspective. Co-created by Deborah Frances-White for The Spontaneity Shop and BBC Radio 4. Produced by Al Riddell. Music by Mark Hodge and Omahrose, produced by Nick Sheldon.
