|How will you measure your life? is the question that Clayton M. Christensen, James Allworth and Karen Dillon set out to answer in this stimulating book, applying management theories to the task of developing a strategy for life. The question was motivated by an observation Christensen made concerning his fellow Harvard Business School alumni: Despite their professional accomplishments, “many of them were clearly unhappy” (Christensen, Allworth, & Dillon, 2012: p. 2). To investigate this matter, the authors apply the study of abstract theory, in the form of statements as to what causes things to happen and why, followed by an application of theory to the examination of the problems and opportunities of a real-world company and, finally, the use of theory to predict what problems and opportunities are likely to occur in that company’s future. They make a compelling argument that, by transferring this approach to the personal sphere, a theory can be developed that can explain and predict the degree of happiness and satisfaction in both the professional and private spheres of an individual’s life—in much the same way as management scholars deploy theories to explain and predict corporate success and failure.
