Do you want to know what "success" really costs? Julia Kessler built a drink brand that sold 10 million units and got into Waitrose and Tesco — then COVID wiped out 70% of her revenue overnight. She reveals the brutal reality of founder identity, why separating yourself from your business is the hardest part of scaling, and how she's rebuilding as a portfolio advisor after a decade of grinding.
