Journalist Jenny Valentish is best known for her deep dives into the human psyche. Her new book, The Introvert's Guide to Leaving the House, is a more introspective successor to Everything Harder Than Everyone Else, which explored the fine line between hedonism and endurance, and her mea culpa memoir Woman of Substances, which was nominated for a Walkley. She writes for the Guardian, the ABC and The Age, and has pressure-tested the wellness industry with her podcast Spirit Levels. Becoming immersed in her book topics has tended to spill over into real-life pursuits, such as Muay Thai fighting and competing in bodybuilding. Maybe this time around she'll become a game show host.
