Recently,  I conducted keynotes for two school-based organizations in different states. Learning about the model of human behavior is typically a highlight for many in the audience.   I shouldn’t be surprised anymore, but it always strikes me that less than 30% of the participating audience has had any type of training to understand personality types.  One of our most critical assets is to be able to effectively communicate with people.  Organizations and businesses rely on individuals to be successful at this skill so they can bring in new customers and retain the existing ones.
