This week's guest is Maria Hatzistefanis, beauty entrepreneur and founder of Rodial.

Building up her business from nothing, after being fired from a job in finance, 19 years later, her skincare companies, Rodial, Nip and Fab and Nip and Man are worldwide brands, backed by the likes of Kylie Jenner.

Basically, if you've got your own business - or are considering taking the plunge - you could do a lot worse than turn to Maria for advice.

She gives advice on everything from 'having it all' to taking risks - and if, after listening, you want more advice, she has a book out, called How To Be an Overnight Success.
