As the author of Relationship Selling, Mr. Cathcart has long been a trend setter in the business community. His belief is that business should be practiced primarily as an act of friendship rather than primarily as a process of negotiation. This concept has come to dominate the business mindset since Mr. Cathcart's book was first published in the mid 1980s. Today he focuses on advancing the two elements that cause businesses to grow: Solutions and Connections.

Mr. Cathcart has found that people who know themselves tend to grow themselves and their businesses more effectively. His two decade long study of applied behavioral science has resulted in The Acorn Principle, a comprehensive work designed to guide readers into an awareness of the many elements that make them who they are. This breakthrough work has achieved bestseller status online as well as through traditional channels in several languages.

Among professional speakers Jim Cathcart is a world leader. Past president of the National Speakers Association (NSA) , winner of the Cavett Award, member of the Speaker Hall of Fame (CPAE), Certified Speaking Professional (CSP), a member of the exclusive Speakers Roundtable, 20 of the world's top speakers, and, in the year 2001, recipient of the Golden Gavel Award from Toastmasters International.
