The book's strength is in its opening discussion about how work fits within our life choices. Although we've been discussing portfolio careers for two decades, Hopson and Ledger's refreshing overview is timely. Their various case studies quickly convey the excitement and risks of the portfolio life. As the book suggests, a portfolio career is not the same as holding down three bad jobs and wishing you had one. The authors bring out several important dimensions: portfolio working is more about cash flow than income, and unlike salaried work there are no upper barriers to earning. Lively and inspiring examples are offered - some eclectic mixtures of freelance and voluntary commitments, others grounded in conventional roles. The downside includes uncertainty, the risk of overwork or a lonely life of self-marketing. The upside is that you're more likely to be working in a way that matches your skills, values and motivation. This book challenges assumptions about the kind of people who might chose this option - not just the semi-retired, middle-aged and financially protected, but younger talent, too - case studies include several people under 30. Full of useful insights, and very much recommended.
