I agree that few people are ‘true’ introverts or extroverts. This is discussed in detail in Susan Cain’s book Quiet. I also find people have a tendency to lean toward one side depending on time of day, their energy level, what’s going on in their personal life, etc. I liked the tip on meeting preparation as I am someone who over-prepares and does not like flying off the cuff, especially in meetings. Thanks for the article!
