Discover how ordinary objects create extraordinary happiness in "Joyful," endorsed by Susan Cain as "having the power to change everything." Selected by Malcolm Gladwell's Next Big Idea Club, this guide reveals ten aesthetics that transform environments into wellsprings of joy.
Ingrid Fetell Lee is a designer, author, and leading expert on the intersection of design and human emotion, best known for her book Joyful: The Surprising Power of Ordinary Things to Create Extraordinary Happiness. Blending industrial design expertise with insights from psychology and neuroscience, her work explores how everyday environments and objects shape our sense of joy.
A former Design Director at global innovation firm IDEO, Lee founded the influential blog The Aesthetics of Joy and has guided brands like Target, Kate Spade, and the US government in creating emotionally resonant experiences.
Her 2018 TED Talk, Where Joy Hides and How to Find It, has garnered over 17 million views and a standing ovation, cementing her status as a visionary voice in positive psychology and design. Lee holds a Master’s in Industrial Design from Pratt Institute and a Bachelor’s in English and Creative Writing from Princeton University.
She has been featured in The New York Times, Fast Company, and Wired, and her research continues to influence how individuals and organizations harness joy through intentional design. Outside her professional work, Lee is known for her love of polka dots, rainbow sprinkles, and an infectious repertoire of happy dances.
Joyful explores how everyday objects, spaces, and sensory experiences—like vibrant colors, playful shapes, and natural elements—can cultivate profound joy. Ingrid Fetell Lee identifies 10 universal "aesthetics of joy," such as Energy, Abundance, and Magic, blending design principles with neuroscience and psychology to show how our surroundings directly impact emotional well-being.
This book is ideal for designers, creatives, and anyone seeking to infuse more delight into their daily lives. It’s also valuable for psychology enthusiasts or individuals interested in how environments shape mood, offering actionable strategies to transform spaces into sources of happiness.
Key concepts include:
Lee describes them as sensory properties—like bursts of color, open spaces, or whimsical contrasts—that universally trigger delight. These elements are rooted in evolutionary biology (e.g., humans gravitate toward lush landscapes for survival) and psychological patterns.
While direct quotes aren’t provided in sources, Lee emphasizes:
Lee suggests practical tweaks:
Some may argue the book prioritizes surface-level aesthetics over deeper emotional work. However, Lee clarifies that joy from surroundings complements—rather than replaces—internal practices like mindfulness.
Unlike mindset-focused guides, Joyful emphasizes external, sensory solutions for happiness. It pairs well with books like The Life-Changing Magic of Tidying Up but stands out for its design-centric approach.
Lee is a designer (Pratt Institute MA), author, and founder of The Aesthetics of Joy blog. A former IDEO design director, her TED Talk on joy has 17+ million views. She merges design expertise with psychology to explore how environments shape emotions.
Yes. Lee cites neuroscience (e.g., how bright colors stimulate the brain’s reward centers) and psychology studies (e.g., nature’s calming effects) to support her theories about joy’s tangible roots.
Abundance refers to lush, multi-layered environments—think confetti, overflowing gardens, or richly decorated spaces—that evoke joy through sensory richness and variety. This aesthetic taps into humans’ evolutionary preference for resource-rich settings.
While not a mental health manual, Lee’s strategies (e.g., incorporating sunlight or playful decor) may complement therapeutic practices by reducing stress and fostering environments that support emotional resilience.
Lee advocates for offices with open spaces (Freedom), colorful accents (Energy), and collaborative, circular seating (Play) to enhance creativity and reduce burnout. These adjustments align with her principles of joy-driven design.
Bursting shapes—like fireworks, starbursts, or radial patterns—symbolize expansion and shared delight. These forms trigger joy by mimicking natural phenomena (e.g., blooming flowers) and cultural symbols of festivity.

Picture a crumbling post-Soviet city where citizens had given up-until someone painted a building bright orange. In Tirana, Albania, Mayor Edi Rama faced empty coffers and demoralized residents. His radical solution? Transforming drab concrete with vibrant colors. The results defied logic: people stopped littering, paid their taxes, and felt safer despite no increase in police. Within five years, businesses tripled. What changed? Nothing material-just color. This moment sparked a revolutionary question: What if joy isn't locked inside our minds but scattered throughout our physical world, waiting to be discovered? We've been taught that happiness comes from within, that detachment from material things brings peace. Yet everywhere, tangible objects create intangible delight-sunsets lift spirits, flowers improve memory, and sunny workspaces help people sleep better. Joy isn't frivolous decoration; it's encoded in ten distinct aesthetics woven into our evolutionary fabric: Energy, Abundance, Freedom, Harmony, Play, Surprise, Transcendence, Magic, Celebration, and Renewal. These aren't arbitrary preferences but survival instincts transformed into sources of delight, revealing that our surroundings don't just reflect our emotions-they actively shape them.
