Bradley Trevor Greive has a touch of the showman about him, but it takes more than a larger-than-life persona to achieve his kind of success. At last count, Greive had sold 30 million books, kicking off with The Blue Day Book series that coupled cute pictures of animals with pithy comments (a combination that puts him way ahead of cat memes on social media). As our interview reveals, beyond big gestures and self-deprecating wit is a man who thinks big, spends much time alone and believes in the power of persistence to realise his sometimes outlandish goals. For a session on how to do it BTG-style, look out for his appearances at the Tasmanian Writers and Readers Festival in Hobart next month. Also this week, we spend a night with fisherman Chris Massie aboard his boat during his solo protest against a fish farm at Okehampton Bay on the East Coast. And we look beyond the gym to a fun and daring form of exercise for adults as well as children.
