Key Discussion Points & Insights

1. What Is Happiness? (04:08)

• Two Main Types:
  • Hedonic happiness: Pursuit of pleasure, avoidance of pain. It’s about momentary joys—think of the pleasure after a compliment or enjoying a delicious meal.
    • “This is like a combination of the feel good stuff…the rush you get from a compliment, the satisfaction of a delicious meal… And then the subtraction of negative stuff like not feeling pain, not feeling sad, not feeling heartbreak.” (05:54, Jemma)
  • Eudaimonic happiness: Living a life aligned with meaning, purpose, and self-realization—originating from Aristotle’s philosophy.
    • “True wellbeing doesn’t come from pleasure alone, but…from fulfilling your deeply seated potential and living a life aligned with your values.” (08:19, Jemma)

2. The PERMA Model of Wellbeing (10:14)

• Developed by Dr. Martin Seligman, PERMA is a framework made up of:
  • Positive Emotion
  • Engagement
  • Relationships
  • Meaning
  • Accomplishment
• “What this theory really says is you need all of them…it’s like trying to make a cake with only two of the ingredients you need.” (14:09, Jemma)

3. Can You Measure Happiness? The Genetic Set Point (17:25)

• Happiness is partly measurable through its components.
• Set Point Theory: Around 50% of happiness is genetic, 10% comes from circumstances, 40% from intentional activities (per Prof. Sonia Lyubomirsky).
  • “We are born with a genetically determined baseline level of happiness that we tend to return to even after major life events.” (19:32, Jemma)
• Most of happiness is within our grasp via intentional activities, not just luck or circumstance.

4. Generational Trends: Are We Becoming Less Happy? (26:19)

• Jemma reflects on personal and generational anxieties about declining happiness in youth.
• The World Happiness Report finds a “noticeable decline in happiness and life satisfaction” for young people since 2010.
  • “For the first time…young adults are less happy than their older counterparts.” (27:36, Jemma)
• Factors include social media, economic instability, loneliness, earlier onset of stress and anxiety, and shifting life expectations.
• The classic “U-shaped curve of happiness” is shifting— 20s are no longer the peak for many.

5. Debunking Myths About Happiness (36:31)

Myth 1: You can be happy all the time.

• “The idea that we should be in a constant state of bliss is not only unrealistic…it’s also deeply unhealthy.” (37:48, Jemma)
• Introduces “emodiversity”: A mix of emotions is essential for psychological health.

Myth 2: Happiness is a destination ("I'll be happy when…")

• “This belief…is a trap, and it is a common one at that. Once we get to that point…we realize we’ve placed a lot of our promise for the future in this goal, and the goalpost just moves further and further.” (41:32, Jemma)
• Hedonic adaptation ensures we return to baseline happiness regardless of positive or negative happenings.

Myth 3: Money will make me happy.

• Cites Daniel Kahneman & Angus Deaton’s study:
  • Well-being rises with income up to ~$110,000 USD today, then plateaus.
  • “Having enough money to meet our basic needs…has a huge, life-changing impact, but beyond that, more money didn’t seem to make a significant difference.” (46:31, Jemma)
• How you spend money matters (see “Pro-Social Spending” below).

6. Actionable Strategies for True Happiness (52:52)

1. Make a “Happiness Blueprint”

• Savor positive moments intentionally. Create a “smile file” on your phone or write memorable experiences down.
  • “This act of savoring helps your brain cement the positive memory and extract maximum joy from that moment.” (53:54, Jemma)

2. Active Constructive Responding

• When people you care about share good news, respond enthusiastically and ask questions to increase joy for both of you.
  • “Enthusiastic responses make both people happier. The way I think of it is like a tennis ball that gets faster and faster… as you hit it back and forth between two people.” (55:35, Jemma)

3. Pro-Social Spending

• Studies (Elizabeth Dunn, Science) show spending money on others boosts happiness more than spending on oneself.
  • “It’s not about spending tons of money… It’s about buying a friend a coffee… a small trinket…leaving just a little extra generous tip.” (57:37, Jemma)

4. Write a Coherent Life Narrative

• Construct stories about your experiences to create meaning, especially out of hardship, giving yourself a sense of agency and coherence.
  • “The story we tell ourselves about our happiness…is incredibly important… When you help people see their life as a story with different chapters, they do feel happier.” (60:08, Jemma)

Notable Quotes & Memorable Moments

• On the myth of constant happiness:

  “The idea that we should be in a constant state of bliss is not only unrealistic… it’s also deeply unhealthy. Life is a full spectrum of emotions.” (37:48, Jemma)

• On emotional diversity:

  “You need to be in touch with all different sides of yourself and how you respond to certain hard and great things in order to feel good.” (39:58, Jemma)

• On hedonic adaptation:

  “Even if a really great thing happens to you, it still doesn’t always feel like it means a lot long term, and you basically get used to the happiness that it initially elicited.” (41:51, Jemma)

• On wealth and happiness:

  “Wealth predisposes you to different kinds of happiness. While wealthy individuals may find greater positivity in their accomplishments, less wealthy individuals seem to find more positivity…in their relationships.” (48:15, Jemma)

• On pro-social spending:

  “Spending money on others consistently activates the brain’s reward centers, producing this warm glow of giving.” (58:28, Jemma)

• On 20-somethings and happiness:

  “For my 20-something listeners… it’s okay if these are not your happiest years. I’ve definitely had some freaking dark, dark times in my 20s… so if you’re really struggling at the moment and thinking, ‘this is it, this is the happiness drop-off,’ firmly and resoundingly, that is not the case. Not at all.” (63:12, Jemma)

Final Thoughts

Jemma wraps the episode by emphasizing that happiness is not about constant joy or ticking off milestones. Instead, it's about savoring the moments, building meaningful relationships, integrating small intentional practices, and embracing the full complexity of the human emotional experience. For those in their 20s, she offers reassurance: these years may be tough, but happiness is not linear, nor reserved for a future version of yourself. Seek out the “glimmers,” become an active participant in your own joy, and remember, happiness is a journey, not a destination.
