Miss Cabane's book is more than just about basic charisma. The book is about how to get in the right internal mental state when faced with adversity. Getting into the right internal mental state is the true message of the book. Miss Cabane's book is similar to that of other writers where there is a bigger message beyond the main theme. For instance, Ramit Sethi's book/blog is purportedly about finance, but his real message is about behavioral change. Cal Newport's book/blog is purportedly about getting straight A's, but his real message is how anyone can train themselves to learn more efficiently. Similarly, Miss Cabane's book teaches you that understanding your internal mental state is the key underpinning of charisma. You will learn techniques that will help you cope and thrive when facing anxiety, uncertainty, and your own mental critic. I cannot emphasize enough what a positive impact the techniques she has gathered can make in your life especially when facing difficult situations. This is especially true if you spend time studying and working on the exercises in the first five chapters of the book. To truly get the most out of this book, you have to continuously work on the exercises.
The purpose of this book is not to fool people with charisma to make them think that you are better than you are. This would be a misinterpretation of Miss Cabane's message. Rather this book helps you understand that it's okay to feel anger, shame, grief, fear, and nervousness. In a way, Miss Cabane teaches you to embrace these negative emotions (Chapter 4). These negative emotions do make us human after all. What she does teach is ways to prevent negative emotions from holding you back. She provides a solution to the question, "how do I realize my potential, given that I get crippled by nerves, shame, and fear?" Therefore, you do not fool people into thinking that you are better than you are. Rather, you just develop a tendency to bring out your best in all circumstances.
