Some books tell the story of how seemingly insignificant things (salt, codfish) changed the world. Poppy King's "Lessons of a Lipstick Queen: Finding and Developing the Great Idea that can Change Your Life" (Atria) takes a more micro view: It tells how a minor accessory changed Ms. King herself—and how it could do the same for you. Alongside guidelines to exploring your entrepreneurial potential, King tells the story of how she went from a teenager alienated by the glossy pink fashions of 1980's Australia to having her own million-dollar makeup line sold at Barneys (and becoming an answer in the Australian edition of Trivial Pursuit in the process). Inspired? That's just what the author intended. "I wrote this because of the hundreds of people over the years who have asked me how on earth I managed to start a lipstick brand at 18," King says. "And then they revealed some great ideas of their own that just needed a gentle push to action. I wanted this book to be that gentle push!"
