Are you missing the bleeding obvious? Viv Groskop talks to Nayna McIntosh, founder and CEO of Hope Fashion, about how we can be so unused to saying what we really want - that we can miss our true calling. She explains that her first retail job was on her mum's market stall, how she went on to work at M&S, Per Una, Next and Asda - and how starting a business is like jumping off a cliff. And she reveals everything she wished she'd know when she started.
