As the boomer generation's hair turns gray, it's not surprising to see retirement advice books like this one, which argues against conventional scenarios. As founder and CEO of New Directions, which coaches older workers on making the transition from working to life after a career, author Corbett points out that boomers' longer life expectancy and better health means that reprioritizing may be more rewarding than simply stopping working. In his first few chapters, Corbett discusses why the concept of retirement needs to be retired, then quickly moves to his central proposal. He encourages readers to focus on building a portfolio of skills, which allows them to shuffle their skills in the same way they would remix a financial portfolio, rather than follow a linear career trajectory. Instead of abandoning work altogether, people can refocus later in life on the preferred skills and meaningful pursuits that suit them best. This insightful and readable book provides not only a convincing argument for the portfolio concept but also concrete instructions on how to get started. If there's a drawback, it's that the subtitle dismisses younger readers who could benefit by putting this plan into action long before reaching age 50.
