What If You Make It To 100? Ideas for Aging In Your 4-Quarter Life

“Gender was to the 20th century what age will be to the 21st: a massive demographic and societal shift that changes… everything.” – Avivah Wittenberg-Cox

In this episode, international thought leader, author, speaker, corporate consultant, and life coach Avivah Wittenberg-Cox reveals the importance of “rebranding” aging: How demographic shifts, the rise of older adults, and an aging workforce have brought us to this unprecedented time in history. In conversation with, Melinda Blau, Avivah proposes a “four-quarter life” framework to help us rethink ageist assumptions. She details the task of each approximately 25 years: growing (Q1), achieving (Q2), becoming (Q3), and harvesting (Q4). As we navigate these territories and encounter new terrain, each of us must become a “skilled transitionist,” which involves using our brains, seeking love and connection in all forms, weathering change, and learning how to make good choices. An advocate of lifelong learning and intergenerational support, Avivah attended Harvard’s Advanced Leadership Initiative (ALI) to spur her own Q3 journey and has since investigated a range of midlife transition programs. Here she tells how they broaden our horizons and can help us transition into new chapters.
