Drawing on Birsel’s year-long codesign research with older people, this book offers readers of all ages—from those in their twenties and thirties just starting out, to those in mid-life looking for a change, to those in later life who are the experts for us all—thought-provoking questions, exercises for self-exploration, and interviews with innovative entrepreneurs and thought-leaders to guide them on their own journeys of crafting the next phase of life. Focusing on four keys areas—Love, Purpose, Well-Being, and Friendship—this book pairs life lessons from people who've lived the longest with design tools to help you plan your own long life, whether you're looking ahead to retirement, a home post-children, or starting a new project that makes you come alive.
