Curiosity Weekly: "Happiness IRL"
Host: Dr. Samantha Yammine ("Sam")
Guest: Dr. Sonia Lyubomirsky
Date: February 25, 2026
Episode Overview
This episode of Curiosity Weekly, hosted by Dr. Samantha Yammine, explores the science behind real-world happiness: what it is, how it's measured, and the practical strategies we can use to achieve more of it. The centerpiece is an insightful interview with Dr. Sonia Lyubomirsky, a leading positive psychology researcher and author, who delves into key findings from her decades of study. Additional segments include surprising research about swearing’s effect on physical performance and a dive into the physics of curling stones.
Key Segments and Insights
1. Swearing and Physical Performance
[01:34–04:36]
- Science Behind Swearing:
- New research from Keele University and the University of Alabama in Huntsville found that swearing can enhance physical performance, specifically strength and endurance.
- Participants performed chair push-ups while repeating either a swear word or a neutral word; those who swore were able to hold longer.
- Possible Explanation:
- Swearing may help enter a "psychological flow" state: boosting self-confidence, reducing inhibitions, increasing focus, and allowing greater physical output.
- Notable Moment:
- Sam reflects humorously:
“I'm definitely a grunter and loud breather at the gym, but maybe it's time to incorporate some swearing into my routine. I wonder what my ultimate power word will be.” (03:58)
- Sam reflects humorously:
2. The Science of Happiness with Dr. Sonia Lyubomirsky
[05:14–24:10]
What is Happiness?
[10:14]
- Defined as having two main components:
- Being happy in your life: Experiencing positive emotions in daily moments.
- Being happy with your life: Feeling satisfied with your life's direction and achievements.
- Notable Quote:
- “...happiness really has two components. And I think about it as being happy in your life and being happy with your life.” — Dr. Sonia Lyubomirsky (10:14)
The Foundation: Connection and Feeling Loved
[06:45–07:53]
- Connection and feeling loved emerged as the most important predictors of happiness across extensive research and interventions.
- Nearly all effective happiness interventions—like gratitude or acts of kindness—work because they deepen feelings of connection.
- Notable Quote:
- “The biggest thing...the key to happiness seems to be...feeling connected and feeling loved.” (06:50)
Quizzes and Mindsets for Love & Connection
[07:53–09:16]
- Dr. Lyubomirsky and her co-author identified five mindsets that foster a feeling of being loved, including “radical curiosity”—genuine interest in the other person.
- Online quizzes, available at howtofeelloved.com, help gauge which mindsets are strongest and which need work.
Misconceptions About Happiness
[12:17–13:46]
- A common misconception: impressing others is the path to feeling loved. In reality, true happiness comes from vulnerability and authentic sharing, not perfection.
- Notable Quote:
- “If you don't really know me, if I'm only showing you these sort of positive parts of myself, I'll always wonder: if you really knew who I am...maybe you wouldn't love me so much.” (13:14)
Cultural and Individual Differences
[11:09–12:17]
- The need to be loved and understood is nearly universal, but cultures and personalities vary in how connection is experienced and expressed.
In-Person vs. Online Connection
[13:46–15:26]
- Online interactions often lack cues for deep connection, can promote oversharing, and may lead to misleading perceptions of others’ happiness.
- College freshmen frequently think everyone else is adjusting better simply due to curated online personas.
External Achievement vs. Lasting Happiness
[15:26–17:47]
- Achievements contribute to happiness mostly in their pursuit (“the journey, not the destination”).
- Intrinsic goals (connection, contribution, personal growth) foster lasting happiness, versus extrinsic goals (money, fame, status), which tend to fuel an endless treadmill.
- Notable Quote:
- “Once you achieve it, people tend to sort of be happy for a little bit, and then they want to achieve the next goal...that's called the hedonic treadmill.” (16:38)
Practical Strategies for Increasing Happiness
[17:47–19:08]
- Research-backed interventions: gratitude, acts of kindness, meaningful goals, meditation, exercise, relationships, spirituality.
- These all tend to increase happiness by boosting connection and feelings of being valued.
- Notable Moment:
- “If you've ever gotten like a text from someone who just says out of the blue, right, like hey, I'm just so grateful you're in my life, isn't that amazing, you know?” — Dr. Sonia Lyubomirsky (19:02)
Adversity and the Value of Challenge
[19:13–20:29]
- Some adversity is actually beneficial—it teaches resilience and appreciation for good times.
- Optimal happiness isn’t about nonstop ease: having some struggles builds depth.
How Much Is Under Our Control?
[20:29–22:34]
- Genetics and circumstance matter, but a significant portion of happiness is shaped by intentional choices and behaviors.
- Deepening connection is a matter of changing the conversation with others—showing warmth, curiosity, and acceptance.
Personal Reflections on Being a Happiness Scientist
[22:34–23:54]
- Dr. Lyubomirsky feels positive about her work’s influence on her own happiness—and acknowledges that while it doesn’t make her perfect, knowing the research helps motivate happier choices.
3. The Science of Curling Stones
[25:18–29:05]
- Why do curling stones “curl” differently than spinning objects like a sliding cup?
- Unique surface friction and microscopic ice scratches combined with stone spin create the signature curve.
- Sweeping by players modifies friction and affects both distance and curl.
- No single physical model explains all aspects of curling—science is still puzzling it out!
- Notable Moment:
- “Watching curling in the Olympics is pretty exciting because it's all about science and strategy.... As you watch those stones glide, just remember there's a lot going on behind the scenes that makes curling a lot more complex than it looks.” (28:38)
Notable Quotes (with Timestamps)
- “The biggest thing...the key to happiness seems to be...feeling connected and feeling loved.”
— Dr. Sonia Lyubomirsky (06:50) - “Happiness really has two components...being happy in your life and being happy with your life.”
— Dr. Sonia Lyubomirsky (10:14) - “If you don't really know me, if I'm only showing you these sort of positive parts of myself, I'll always wonder: if you really knew who I am...maybe you wouldn't love me so much.”

Summary Takeaways
- Swearing can boost physical performance by fostering a confident, low-inhibition mental state.

- Both adversity and intentional positive practices contribute to lasting happiness.
- Much of our happiness truly is within our control, particularly through how we nurture our relationships.
- Curling is much more scientifically complex than it appears—the physics is still being unraveled!
