CHERRY HILL, NJ – October 02, 2026 – Entrepreneur, agency builder and nationally recognized sales leader Dr. Jessica C. Parker has achieved No. 1 bestseller status with “The NO to YES Principle: How to Use Rejection, Adversity, and Discipline to Build a Seven-Figure Sales Career.”

The book presents rejection as a necessary part of professional development rather than evidence of failure. Drawing from nearly two decades in the insurance industry, Parker teaches sales professionals, entrepreneurs, and emerging leaders how to strengthen resilience, act despite fear, and remain disciplined until consistent effort produces measurable results.

“The professionals who succeed are not always the most talented,” Parker said. “They are often the ones who refuse to quit before their results catch up with their effort.”

About the Book

“The NO to YES Principle” was inspired by Parker’s journey from personal hardship and repeated rejection to building a seven-figure agency and developing successful sales leaders.

The book addresses a challenge faced by professionals across many industries: how to process rejection without allowing it to damage confidence, identity, or performance. Parker explains that rejection is not a final judgment. It is training that develops the emotional endurance required to succeed in sales, leadership and business.

Through practical instruction and real-world experience, Parker teaches readers how to take action while afraid, approach selling as service, and communicate more effectively through the 5 Sales Languages.

Unlike books centered only on motivation, “The NO to YES Principle” combines mindset development with actionable sales and communication strategies.

Who Is This Book For?

The book is written for sales professionals, insurance agents, entrepreneurs, business owners, agency builders, coaches, corporate professionals, and leaders who regularly face rejection, uncertainty, or performance pressure.

It also supports professionals who have valuable services and strong ideas but struggle with confidence, follow-up, consistency, or the emotional demands of selling.

• Separate rejection from personal identity and professional ability.
