Jim Jensen began his career as a salesman with Encyclopaedia Brittanica in his senior year of college. Within seven years he had become International Sales Manager in charge of worldwide sales. At the age of 28, he became Senior Vice President and CEO of Great Books of the Western World, a division of Encyclopaedia Brittanica. In this same year (1969) Jim and his wife, Jeri, attended a 4 day seminar that would have an incredible impact on his life forever. As is written in the Introduction, Jim became both a voracious student and, ultimately, teacher of many of the principles written in his book, 7 KEYS To Unlock Your Full Potential.
