Author Craig Crawford, in his book "The Politics of Life: 25 Rules for Survival in a Brutal and Manipulative World" (2007), describes Cher as "a model of flexible career management", and relates her career successes to a constant reshaping of her image according to the evolving trends of popular culture. He further explains that she billed "each dramatic turnaround of style as another example of rebellion—an image that allowed her to make calculated changes while appearing to be consistent." Author Grant McCracken stated, "The term 'reinvention' is now often used to talk about the careers of American celebrities. But in Cher's case, it is particularly apt she is inclined to lock on to each new fashion wave is swept violently down the diffusion stream and out of fashion. Only substantial re-creation permits her to return to stardom." Her "integrity" and "perseverance" are highlighted in the "Reaching Your Goals" book series of illustrated inspirational stories for children, in which her life is detailed emphasizing the importance of self-actualization: "For years, Cher worked hard to become a successful singer. Then she worked hard to become an actress. Even when she needed money, she turned down movie roles that weren't right for her. Her goal has always been to be a good actress, not just a rich and famous one."
