THE 100 YEAR LIFE BY LYNDA GRATTON & ANDREW J. SCOTT

Key Concepts: The Longevity Imperative
Gratton and Scott provide a framework for thriving across ten decades by managing both tangible and intangible assets:

• The End of the Three-Stage Life: The traditional model (Education → Work → Retirement) is collapsing. It is being replaced by a Multi-Stage Life where age and activity are no longer disconnected, allowing for varied phases of exploration and transition at any age.
• The Rise of Intangible Assets: Money isn't enough to sustain a 100-year journey. You must actively manage three types of "invisible wealth":
• Productive Assets: Your ongoing skills, knowledge, and professional reputation.
• Vitality Assets: Your physical and mental health, plus deep, regenerative friendships.
• Transformational Assets: Your self-knowledge and the ability to navigate major life transitions and identity shifts.

• Re-creation over Recreation: Leisure time in a long life can no longer be just about passive relaxation. It must be used for "re-creation"—investing in learning, building networks, and maintaining health to remain productive into your 80s.
• The "Explorer" and "Independent Producer" Stages: New life phases are emerging, such as a youthful period of travel and self-discovery (The Explorer) or a mid-to-late life phase of freelance, entrepreneurial work (The Independent Producer).
• Partnering for Longevity: Long-term relationships must become more flexible, with partners taking turns to support the household while the other takes a break to upskill or pursue a new career path.
• The Resilience Requirement: In a century-long life, industries will rise and fall. Success is determined by your "elastic identity"—the willingness to let go of old versions of yourself and remain an "apprentice of life" forever.
