The book's 100 chapters each cover one of the 100 things that the author suggests successful people do in a couple of pages. A reviewer writes: "the book, subtitled Little Exercises For Successful Living, is easily digestible (perhaps even as a tip a day), with each spread over two pages – the first explaining the concept and the second featuring practical exercises and activities to apply it to your life."^[21] Another adds: "each secret to success is a powerful reminder of the ways you can make your life – and other's – more satisfied, at work, at home and in your relationships, with your health, wealth and in retirement."^[22]
