The author explores the self-realization opportunities possible through second careers as well as the uncertainties and hazards involved in such a major life change. Numerous examples of middle-aged second careerists are included in the book as well as some classic examples. There is no set pattern of career changing in mid-life; new directions and the reasons for shifts are as diverse as the people. The book opens the door to those who feel "bound to their wrong choice, caught in a dead end, and/or victimized by the rat race." One chapter focuses on the need to train people for a cluster of occupations in our technologically changing society that suggests more job changes for the future. Disillusionment with materialistic values and the trends toward social service are often motivating factors for second career choices of a more altruistic endeavor. More women than ever are looking forward to or moving into second careers; retirement, and today's trend toward early retirement, is yet another life stage that can launch a second career. This intimate glimpse at the lives of hundreds of men and women who began new careers (and the psychologists, family counselors, and employment agents who advised them) provides encouragement and identification for those seeking a similar choice.
