One of the biggest misconceptions people have is that only shy people are introverts, and all introverts are shy. Being a non-shy introvert this is a point of interest for me, and this book does a good job at distinguishing introversion from shyness. 
 In addition to a general overview of how an introvert's brain works, the author goes over different scenarios offering insight from a introvert perspective. These include going to parties, and talking on the phone. For each scenario she explains the introvert's mindset, followed by tips on dealing with the situation. Such as stepping away to recharge. 
 The book also identified several other characteristics that I can identify with but didn't realize were related to introversion. Other characteristics include: being hypersensitive, slow decision making, overly analytical, always have a plan, lack of emotional expression or at least not having a smile as the default, preferring emails for complex issues and why they are long winded. 
 The book also covers other misconceptions, such introverts not needing or wanting social interactions. We all have social requirements, we just require different types. It also warns of the dangers is using introversion as an excuse and hiding behind it. 
 If you think you're an introvert or have a friend who is and you want to understand them better. This book is worth a read. Our society favours extroverts so was a it good and refreshing read.
