Book Review: The Introvert Advantage How to Thrive in an Extrovert World by Marti Olsen Laney, Psy.D.
Published: September 18, 2026
I stumbled across The Introvert Advantage on a bookstore date with one of my friends. We will occasionally do book store crawls where we hit 3-4 different local book stores in one day. I love it- it’s an energizing day fueled with supporting local businesses and making connections. I also get a TON of new-to-me books.

The book was originally published in 2002 but it sparked my interest still as I doubted much has changed in introvert-related-science in the last 24 years. I’ve always considered myself an introvert due to my lack of interest to be around people (pretty big indicator), but I’ve never delved further into this personality trait of mine.. Until now.
“Introverts, are energized by the internal world- by ideas, impressions and emotions. Counter to our stereotypes of introverts, they are not necessarily quiet or withdrawn, but their focus is inside their heads.”
What is an introvert?
According to WebMD, an introvert is a person with qualities of a personality type known as introversion, which means that they feel more comfortable focusing on their inner thoughts and ideas, rather than what’s happening externally. They enjoy spending time with just one or two people, rather than large groups or crowds.
When you hear the word introvert, you might think of someone who's shy or quiet and prefers to be alone. While that may be true for some introverts, there's much more to this personality type. Whether you're an introvert or an extrovert all depends on how you process the world around you.
The Introvert Advantage was an eye opener. Like holy shit why didn’t I look into this before!? I was amazed by how detailed Dr. Laney went into the various personality traits of an introvert and how much I related to it.
I assumed my fear of phones or chronic over thinking came back to anxiety or personal character flaws, but these quirks are textbook introverted characteristics. While learning this about myself doesn’t make the world easier to navigate I do feel like I have better tools to work with going forward.
She provides questions to ask yourself to check your temperament and assess your energy levels before heading out into the world. Below were some of my favorites.
What is my mental energy level? Alert? Fuzzy? Brain dead?
What is my body energy level? Pooped? Pert? Peppy?
What do I have to do today? What is optional?
What do I need today?
The list is comprehensive and includes questions for varying energy levels! The list started my brain up with thinking about the extroversions that I genuinely enjoy. I’ve noted I seem to enjoy shopping (which thankfully encompasses farmers markets and local book stores… as opposed to Wal-Marts), so I think I’ll try to be more present when I go shopping and see how I feel. I am notorious for over extending out of the feeling that I have to. It’s a breath of fresh air to have a professional tell me it’s ok to step back and to hone in on what activities give me energy and which ones take it away.
If introverts don’t realize they are overextending, they can become ill. They don’t even realize until their bodies break down that they are running on anxiety and adrenaline.
Dr. Laney also dives into relationship dynamics with ‘innie’ (introverted) and ‘outie’ (extroverted) partners and parenting to help you navigate whatever the dynamic is in your relationship.
While some of the chapters didn’t relate to me, I took in the entire book not wanting to miss a secret. I fully appreciated the chapters on surviving in an extroverted world and how to navigate the social requirements of jobs or friends. I have the book tabbed and will be a vital resource while I enter into the next chapter of my adult life- now better prepared for whatever the world wants to throw at me. At times, I caught myself getting anxious when Dr. Laney would talk about going to parties and networking events so I know where my triggers lie and now have tools to work with them.
Some parts of the book were a bit dated, there was no social media like we have today back then, for example but other then a few dated internet references the information in this book still felt very relevant and valuable.
Out of curiosity, I checked out the website for the book: https://www.theintrovertadvantage.com/
This was a pleasant trip back in time to when the internet was a simple place, the website is frozen in time and while it hasn’t seen an update since 2009 I appreciate that Dr. Laney has kept it up and running after all these years. It’s super cute, check it out.
I recommend this book to every introvert out there- it will help you understand yourself better then you could imagine. It’s also a great resource for extroverts who have an introverted loved one. It’s estimated that 1 in 3 people are introverts.
This book will be a permanent reference book for my shelves and I give it 5 stars.
⭐⭐⭐⭐⭐
