Meet Nancy Ancowitz, business communication coach and author of "Self-Promotion for Introverts®." Though she may not be "loud," she most certainly is "proud" to be a member of 50% of the population who are introverted. Nancy sits down with Dr. Gluck to talk about what introversion is, what its advantages are, and what introverts (such as Barack Obama) can do to further their professional lives in a world that often favors extroverts. www.nancyancowitz.com | www.selfpromotionforintroverts.com
