“I wish my husband never read your book,” a friend said to me some years ago, referring to Working Identity, my book about how people make career changes at mid-career.

The package was generous: It paid him well enough that he was able to explore some of his entrepreneurial ideas for two years, notably one that he’d been dreaming about for years: starting a wine business.
