What if the real barrier to success isn’t your product, your client, or the market, but something deeper? What if the path to greater sales, purpose, and happiness begins not with strategy, but with awakening, an awakening inside you? Selling Joy is not just a book about sales; it’s an invitation to rediscover meaning, purpose, and presence in your professional life. It suggests that the greatest sale you will ever make is the one you make to yourself, the belief that your work matters, and that you matter.

David Adelberg spent decades chasing numbers, recognition, and success. But at the height of his career, it all began to feel empty. A single conversation changed everything. He realized that success isn’t something you pursue, it’s something you align with. When selling comes from belief and service, joy becomes the natural outcome.

Through memorable real-life stories, some humorous, others deeply moving. David shares lessons about the human side of selling:

A boy’s “dog for sale” sign that proved value begins with belief.

A dinner table moment where confidence spoke louder than persuasion.

An encounter in a shoe store where empathy sold more than technique.

A moment of despair that transformed into his most successful day.

These stories lead to four guiding principles:

Belief, You must believe in what you offer.

Service, True success comes from helping others win.

Presence, When you show up fully, people feel it.

Joy, The result when belief and service align.

The message is simple yet transformative: joy is not the reward for achieving success, joy is the source of success. When you stop chasing approval and instead connect with genuine care, selling becomes effortless, natural, and deeply human.

This book is for salespeople, entrepreneurs, and anyone seeking more meaning in their work and life. When you take joy seriously, everything shifts, your energy, your relationships, your results.

Welcome to the rest of your life.
