While we were beginning our Amway business, I read Personality Plus by Florence Littauer. It was a fabulous book. I learned much about myself and others. The book afforded me insight about what others saw when they observed my actions and heard me speak. You can print the personality test and take it without reading the book though I would recommend reading the book. The test alone will tell you what personality blend you have but the descriptions of each personality type is explained in the book.
I am a Melancholy/Choleric. What are you?
