Mark Edwards has two parallel careers - as a journalist and as a trainer/ life coach. As a journalist he began his career writing on magazines, including The Face, Arena, GQ, Esquire and Blitz. For the past 25 years his work has appeared virtually every week in the Sunday Times, and for twelve of those years he was the paper's chief pop music critic. As a coach and trainer, he works with individuals to help them live with more purpose and meaning, and with some of the country's most successful companies, helping them to support and develop future leaders. All of his work is informed by mindfulness, and the Buddhist insights that underpin it.
