When do you become an adult? What does it mean to grow up? And what are the experiences that propel us forward--or keep us stuck?

As we get older, we pass many milestones, but for some of us it can feel as if adulthood is always just out of reach.

Journalist and psychotherapist-in-training Moya Sarner goes on a journey into what growing up really involves, and how we do it again and again throughout our lives. She draws on case studies, as well as her training, and theories of child psychology, psychoanalysis, neuroscience, and more, to explore what it means to be a "grown up" and how we can meet the challenges and opportunities of every stage of our lives.
