In a world where children are often bombarded with messages about how they “should” look, act, or feel, Happiness is the Key, the debut children’s book by award-winning nurse educator and author Dr. Rachael E. Lattanzio, arrives as a radiant beacon of encouragement and empowerment. With enchanting illustrations by Lam Luong, a talented illustrator and nurse, and lyrical, rhyming text that feels like a warm embrace, this heartwarming picture book reminds readers, both young and old, that the qualities making us different are the ones that make us extraordinary.

At its heart, Happiness is the Key is a love letter from a parent to a child, but its universal message speaks to anyone who has ever felt out of place, questioned their worth, or wondered if they belong. Through whimsical storytelling and vibrant artwork, it invites readers to embrace their individuality, follow their dreams, and see the beauty in exactly who they are.

A Story That Celebrates What Makes Us Unique

Happiness is the Key is more than a children’s book—it’s an experience. It captures the tender moments of reassurance and connection between parent and child, while also providing an empowering anthem for self-love. Readers are guided through a poetic journey that transforms the feeling of being “different” into a source of pride and joy.

The story’s gentle rhymes create a melodic rhythm that captures the imagination of children ages 4–10, making it ideal for bedtime stories, classroom read-alouds, or meaningful family moments. Lam Luong’s illustrations bring each page to life with a vibrant palette and whimsical charm, adding layers of emotional depth and wonder to the book’s timeless message.

Why This Book Matters Now More Than Ever

Dr. Lattanzio was inspired to write Happiness is the Key after watching her two daughters, Ella and Laela, navigate the challenges of growing up in a world that sometimes makes children question their worth. She wanted to give them—and children everywhere—a tangible reminder that happiness doesn’t come from comparison, but from embracing exactly who they are.

“In my work as a nurse educator, I’ve seen how self-belief and self-worth can shape a person’s path,” says Dr. Lattanzio. “I wanted to plant those seeds early, in a way that would be memorable, comforting, and inspiring for children and the adults who love them.”

The book’s message is deeply relevant in today’s climate, where conversations about self-esteem, inclusion, and emotional wellness are more important than ever. By addressing these themes in a gentle, affirming way, Happiness is the Key creates a safe space for readers to reflect, connect, and celebrate their individuality.

Happiness is the Key resonates with multiple audiences:

• Children ages 4–10 — Especially during formative years when identity and confidence are developing.
