Gail Sheehy’s 1976 book “Passages” had an exciting idea at its core: adulthood is dotted with predictable turning points. Now, after more than 45 years interviewing women and men about their lives, the journalist and best-selling author has turned the lens on herself. Her new memoir reflects on her career as a trailblazing female journalist in the '60s, a mother determined to balance work and family and a caregiver to an ailing husband. It was through this look back at her own passages that Sheehy came to realize what the theme of her life has been: “daring." Gail Sheehy on life’s passages, and the daring that’s gotten her through them.
