I recently finished reading The Let Them Theory by Mel Robbins. This is my work's book club choice for the quarter.

"What if the key to happiness, success, and love was as simple as two words?
If you've ever felt stuck, overwhelmed, or frustrated with where you are, the problem isn't you. The problem is the power you give to other people. Two simple words—Let Them—will set you free. Free from the opinions, drama, and judgments of others. Free from the exhausting cycle of trying to manage everything and everyone around you. The Let Them Theory puts the power to create a life you love back in your hands—and this book will show you exactly how to do it.
In her latest groundbreaking book, The Let Them Theory, Mel Robbins—New York Times bestselling author and one of the world's most respected experts on motivation, confidence, and mindset—teaches you how to stop wasting energy on what you can't control and start focusing on what truly YOU.

Whether you want to advance your career, motivate others to change, take creative risks, find deeper connections, build better habits, start a new chapter, or simply create more happiness in your life and relationships, this book gives you the mindset and tools to unlock your full potential."
I went into this book expecting A LOT! I adore Mel Robbins, I love what she talks about, I always feel that she is right on, and she is no-nonsense. This book just didn’t resonate with me as much. I feel that the “Let Them” theory could have been easily read in one article or listened to in one podcast (which is how this book came to be). This 300-page book was unnecessary and a bit redundant.
Basically, the “Let Them” theory is to stop letting other people hold power over you. Let them, or him/her, think, do, and feel what they want- and you can continue being you. We can never control another person, only ourselves. Which brings us to Let Them = Let Me, in which Robbins goes into great detail on how to act with that theory.
In this book (Chapter 8, specifically), Robbins goes on to explain how most people have the emotional capacity of an eight-year-old, and I couldn’t agree more. In which she explains that we have to let people go off and have their tantrums, and sulk in the corners if they want to.
One thing that stood out the most to me in this book was the ABC LOOP:
A- Apologize: then ask open-ended questions
B- Back Off: and observe their behavior
C: Celebrate progress while you continue to model the change
I feel that this is a great method for dealing with people that you want to continue having a relationship with.
All in all, the Conclusion of the book was probably the best chapter for me, and the whole book was pretty much summed up in the conclusion… With that, I will leave you with a quote that I really liked and resonated with.
“You’ve wasted so many years being so consumed with other people, their feelings, their thoughts, and what they’re doing. So let this book be your wake-up call; you are in charge.”
Check out The Let Them Theory, and discover what happens when you let them.
Happy Reading :)
