From Rock Bottom to Radiance: Jean-Sébastien Busque Releases “My Apple Pie of Happiness” — A Heartfelt Guide to Rediscovering Joy

A former industrial engineer and corporate leader, Busque was once praised as the “boss everyone wanted”—muffins included. But beneath the surface of professional success, life unraveled. “I thought I knew happiness,” Busque shares. “But I was settling for a bland pie, until I discovered the secret ingredient: love. Self-love. Love for our life. Love for our wounds. Love for who we are. Suddenly, everything changed.”

That transformation—messy, bold, and profoundly human—is at the heart of My Apple Pie of Happiness. Through 40 bite-sized life lessons, Busque offers practical tools, deep reflections, and a generous dose of laughter. The book is a lifeline for anyone facing chaos, feeling stuck, or simply hungry for something real.

More than just a self-help book, My Apple Pie of Happiness is a mirror and a map. It helps readers reclaim their joy and peace of mind, no matter the season of life they’re in. Busque’s raw storytelling style makes even life’s heaviest topics feel safe and surprisingly light.

“You are so young to have faced all of this! Your book made me laugh, made me cry, but most of all, you made me realize that sometimes it’s the small tidbits of life that actually bring us closer to happiness,” says Sara D.

As a Business and Life Transformation Expert, Busque now guides others from chaos to clarity, offering coaching, corporate workshops, and one-on-one mentoring rooted in vulnerability, alignment, and fearless truth.

“I want people to know that you don’t have to have it all figured out to begin again,”Busque says. “You just have to be willing to look honestly at where you are, and take the first step, however small, toward joy.”

Whether you’re reinventing your life, rebuilding your career, or simply feeling like something’s missing, My Apple Pie of Happiness is a reminder that happiness doesn’t need to be chased. It can be created, ingredient by ingredient.
