This concluding chapter revisits some of the main themes of the book. Transition expertise is discussed through the lenses of cognitive adaptability, personal intelligences, contextual intelligence, and motivation. Career transitions are discussed through the themes of self concept evolution and identity change. The methodological characteristics of the study are evaluated, including its limitations. The questions of control group, nontransitions, and failed transitions are addressed. Finally, avenues of future research are proposed, including self-efficacity and self-control, resiliency, and wisdom. The discussion is informed by the retrospective interviews with twenty-four elite performers in three domains (business, sports, and music) who successfully and repeatedly transitioned to higher positions within their field.
