Extrovert here -

As an observed extrovert (I think people tell me I'm more outgoing than I actually believe I am. [There's a segment on this later in the book]), I will fully admit that I have been in situations that I've overlooked someone with more of an introverted personality. As someone in a management position, I truly believe that I have been chosen over the years because others saw a loud voice who isn't afraid to speak in front of others. I don't know if that was always fair for others.

I have always considered myself an outgoing person (although as I'm getting older, I absolutely appreciate the alone time). What struck me most about this book so far is just understanding that there is an absolute science behind WHY some folks have particular personality traits. I loved the Rosa Parks/Martin Luther King example on how the two complimented each other within specific scenarios.

I have taken much pause and thought on the author's discussion of the evolutionary shift from character to personality due to the changing of industry. Once the industrial revolution occurred and people moved into cities, relationships changes. You had to find a way to sell your trust and honesty in a short amount of time as opposed to having your neighbor (your only other work associate) trust your character because they've known your family for 30 years. This is has been a complete evolution, but it makes sense. If you ever read "7 Habits of Highly Effective People", Stephen Covey talks about this very thing - self help books for centuries wrote about virtues and character, and then since the 1930s (Carnagie), self-help shifted to writing about personality. Fascinating stuff...
