In all my years in business and the thousands of people I have interacted with, I have only met a handful people who I would consider truly evil people. However, they were most definitely evil people who did everything in their power to leave a wake of destruction in their paths. I have not, to this day, understood why they would do the things they did other than the simple fact that they truly were evil.
In trying to come to grips with these people and determine how to handle them, I turned to Dr. Henry Cloud . . . my favorite psychologist. Although I have never met Dr. Cloud, I consider him a mentor and I have used his books and videos extensively over the years.
