Johann Hari is giving me career advice. This isn’t part of the plan. But as you already know if you’ve read one of the British author’s three bestsellers – “self-help” for the addicted, depressed and distracted – Hari can suggest an expert for every problem.

“When I’m doing my job well, I think of myself as a concierge,” he says, sitting in the corner of Sydney’s original brunch spot, Bills, in Darlinghurst. “For me, always the happiest moment with any of my books … is when one of the experts I’ve written about, emails me and says, ‘oh people have read your book and are emailing me’. Because I’m like, ‘ah, I connected you with the people who need you’. My job is to find those people.”
