He interviewed James Dyson about the Japanese and perfection; a picture framing expert about working with Madonna, Francis Bacon and David Bailey; a philanthropist who gives 75% of what he earns to charity; and the man who makes staircases for the Queen Elizabeth II, Sheikh Maktoum and Adnan Khashoggi. His Secret of Success column appeared in The Daily Telegraph, but he also writes for a variety of business, consumer and contract magazines about business, management and entrepreneurship.
