Charlie had the gift of taking some very complex concepts and making them much more simple during the implementation process. In fact, some of his explanations were so simple, people would not believe that they would work (i.e. just flick the hand out of the starting blocks and everything will take care of itself).
On the other hand, I would be talking with Charlie and the nature of the conversation was so advanced, I would just keeping nodding my head in agreement even though I had no freaking clue what he was talking about. The concepts would be zooming over my head at the speed of a supersonic jet fighter. In most cases, it would take me a number of years to actually understand the message he was trying to impart.
When we would do his seminars together, I would always introduce myself as the “translator” or “CF for Dummies” when we got to the high-end discussions on training. Charlie would introduce himself as “Rain Man”. I guess that would make me Tom Cruise.
