Date: November 24, 2025
Host: Peter Attia, MD
Guest: Walter Green (author, philanthropist, founder of the Say It Now movement)

Episode Overview

This deeply personal and reflective episode centers on the transformative power of gratitude, the importance of expressing appreciation during life rather than after, and how living with intentionality can reshape relationships, legacy, and personal peace—especially when confronting mortality. Walter Green draws on his own unlikely journey: from a turbulent childhood to building meaningful relationships later in life and ultimately launching the “Say It Now” movement, which encourages people to publicly acknowledge those who made a positive impact on them, before it’s too late.

Key Discussion Points & Insights

1. The Making of Walter Green: Early Life and Influence of Loss

• Challenging Beginnings (06:34–13:49)

  • Frequent family moves and parental illness in childhood resulted in little opportunity for close friendships and a persistent awareness of life’s unpredictability.
  • Father's early death at 53 branded Green with a sense of urgency and the importance of not postponing meaningful actions or words.
  • “The gift that I got was this incredible branding that life is short, it’s unpredictable, you never know. And from then on, I’ve been walking up escalators. That’s the way I live.” – Walter (11:38)

• Struggles with Mental Health (13:49–18:45)

  • Hospitalized for a breakdown in his early 20s after a crisis at work—a formative, humbling experience that made him "afraid of failing and I failed and I survived."
  • Spent years in therapy, emerging with greater self-awareness and empathy.

2. Building a Life of Relationships and Authenticity

• Cultivating Friendship & Expressing Gratitude (23:48–27:51)

  • After decades of rootlessness, Green focused on developing authentic friendships in midlife.
  • For his 50th birthday, rather than centering the celebration on himself, he honored close friends with public tributes detailing their personal impact.
  • Deliberate, personalized gestures—like sending apples with event invitations and writing brief summaries of how each person had enriched his life—left a lasting effect on everyone involved.
  • “People appreciate being appreciated, and made more so when you do it publicly.” – Walter (27:18)

• The Power of Public Appreciation (29:46–30:52)

  • Drawing from decades in the conference business, Green recognized the amplified emotional impact when gratitude was expressed before an audience.

3. Living Intentionally and Saying No

• Intentionality as a Guiding Principle (31:30–36:45)

  • Living with the urgency from his father’s early death, Green shifted from saying yes to all opportunities to becoming highly selective, focusing on what was truly meaningful.
  • Adopted a process of “thinking in reverse”—first clarifying desired outcomes in any endeavor or interaction, then working backwards to determine what actions align.
  • “I always think in reverse… If this conversation is really successful, what would have happened by the end of it for us to know that our time was well spent?” – Walter (33:41)

• Benchmarks and Boundaries (36:54–39:53)

  • Regularly assesses all life areas (personal, family, finance, health) and sets benchmarks, which becomes the filter for what to accept or decline: “It is so easy for me to say no when it isn’t consistent with the outcomes and the indicators that I’ve been committed to.” – Walter (38:09)

4. Embracing Mortality and the "Say It Now" Movement

• Seizing the Moment Before It’s Too Late (40:23–47:15)

  • Inspired by notable stories (Tim Russert’s funeral, “Tuesdays with Morrie”, and his father’s early demise), Green resolved not to wait for deathbeds and funerals to express appreciation.
  • For his 70th birthday, he visited 44 people worldwide who had shaped his life, sharing with each, specifically and personally, what they had meant to him—recording and following up with written mementos.

• The Four-Base Process for Living Tributes

  • 1. How they met
  • 2. Shared experiences
  • 3. Detailed account of the person’s impact, with specifics
  • 4. Ask the recipient for honest feedback: “If you could give me one piece that would create a mosaic about who I am, what would that piece have been from your perspective?”

5. From Personal Practice to Global Movement

• From Private Journey to “Say It Now” Initiative (48:19–51:22, 61:44–67:07)

  • The positive effects led to the founding of the Say It Now movement—teaching people to express gratitude in real time.
  • Now in tens of thousands of classrooms globally, with tailored tools and resources to encourage people of all ages to practice public gratitude.

• Life-Changing and Even Life-Saving Impact

  • Shared stories of feedback—such as a reader in the Philippines who chose not to end her life after reflecting on people who helped her—demonstrating the movement’s far-reaching impact.
  • “They all broke into applause...maybe this story has to be told more. Maybe it shouldn’t just be a personal story.” – Walter (48:19)

6. The Essence of Relationships and Legacy

• Why Deep Friendships Matter (53:10–57:38)

  • Green points to the emptiness some experience despite wealth and “friendships,” concluding that authentic, deep relationships—not superficial associations or experiences—enrich life.
  • The habit of “being current” in his connections—always telling people what they mean to him and keeping relationships up-to-date—gives lasting peace.

• Training and Modeling for the Next Generation

  • Emphasizes the power of modeling behavior for children and mentees: “I have had evidence that the modeling is more important than the speaking. I’m very proud of them, and I think they get the message...” – Walter (73:19)

7. Finishing Strong & Last Years’ Wisdom

• Embracing Mortality With Peace (68:19–71:06, 76:37–78:56)

  • When faced with serious health scares, Green operationalizes what “finishing strong” looks like: organizing finances, updating relationships, expressing everything left unsaid, planning for his spouse’s comfort, and accelerating generosity—ensuring nothing important remains undone.
  • “If you can build that—this awareness and expression of gratitude…you will be enriched by expressing it and the person receiving it will be.” – Walter (78:56)

• Purpose vs. Passing Time (82:32–83:14)

  • “For me, it’s purpose time. You give me time, it’s purpose time.” – Walter (82:53)
  • Finds fulfillment in serving others and working on meaningful projects, regarding “unfinished symphonies” not as failures but as markers of a life rich with purpose.

• Link Between Purpose and Longevity (81:13–83:14)

  • Peter and Walter reflect on how continuing to serve, support others, or simply have “purpose” may be crucial for living longer and living well.
