Try, why not

I really enjoyed this book. I mostly bought it for my girlfriend. We have been going through a lot of emotions over the death of our child. I honestly didn't finish the entire book. Lots of crying. Lots of epiphanies. Lots of self discovery.

Just get it!

Good book! It was recommended by a friend several times but it took me a while to want to read it. I was worried it would be another self help book, teaching people to be super selfish. But it wasn’t! I was very impressed with the writing and the teachings. I have purchased two more copies to give as gifts.

Let Them.... Let Me!!!!

The mindshift of the Let Them Theory is so helpful and the way Mel Robbins writes is so relatable. If you are one who loves to do self work and maybe needs a reminder of how to handle things or if you are seeking a different way to look at situations this is an easy book to read and take away from.This is simply a book that holds the mirror up and its up to you to take a look and see what you can do to change the outcome you're looking for.

Good advice!

I have to admit, I had never heard of this author before though I am definitely not new to self help books! I guess I just read so many in my 30's to 60's that I haven't kept up. I did like this though and recommended it to family and friends. It is an easy listen and while it took me awhile to get accustomed to her voice, I did like the professional she interviewed and thought there was a lot there. Dealing with the present is really about all most of us want or have time for, not a replay of all past hurts and wounds. Keep it simple stupid is still a good theory and the Let them theory goes well with that advice!

Not what I was hoping for

Wanted to love the book and thought it would be a mental game changer and the first chapter was but the rest was just a lot repeating of words that caused me to lose interest and so I have not finished the book yet. I love her podcasts and thought I would love this too but it just didn't hit the mark for me

(SHOUTING) LET THEM!! Insert eye roll at the drama queens

⭐️⭐️⭐️⭐️⭐️Honestly, I wasn’t sure what to expect from "The Let Them Theory," but I think the author secretly snuck into my brain and then decided to write a book about it. Every page feels like a gentle slap on the back, telling me to chill out and let people be. My friends are now worried I’ve become a zen master overnight—mainly because I’ve started nodding sagely every time someone complains. If you’ve ever wanted a manual on how to mind your own business without turning into a hermit, this book is your new best friend. Warning: reading it may cause spontaneous eye-rolls at drama queens and an uncontrollable urge to shout “Let them!” at random intervals. Five stars for making me laugh, think, and finally give the universe some peace—and maybe a little space for everyone to be weird.

Game Changer for a balanced life

On page 30 and already finding motivation from this book. I’m generally the one that my family comes to, somehow I was born the “fixer” and as an almost 40 year old with a husband and 3 children, being the fixer has become absolutely exhausting. I’m now working towards backing out of this role and finding a better balance for peace and happiness as it relates to my personal life and goals. This book is already doing what it was designed to do, spark change and courage to do something different. I love it!

Empowering

I've been a long time follower and Mel Robbins fan and devotee of her podcast. It is truly an empowering feeling to know how to take your power back and give energy and attention to areas that matter most in life by setting boundaries and having hard conversations and doing the inner work to heal yourself, reclaim power, and give yourself the love you deserve. Mel Robbins breaks it down into actionable steps. I wish I had her tools and wisdom at certain points in my life but she makes it possible by simply believing in yourself. A truly remarkable read for anyone struggling in any phase of their life.

Insightful

Let Them Theory is one of those rare books that's both an easy read and packed with insight. The writing is clear and accessible, but the ideas stay with you long after you put it down. It challenges how we think—about people, power, and the way we make meaning—without feeling overwhelming or academic. Whether you're new to theory or just want a fresh perspective, this book is thoughtful, engaging, and surprisingly empowering. Highly recommended!

This book is transformative. BIG love to you, Mel.

This book is a game-changer!

This book is absolutely amazing—hands down one of the most impactful reads I’ve picked up in a long time! I devoured it over a weekend and immediately grabbed the audiobook so I could listen to it again during my commute. That’s how much it resonated with me.I wouldn’t call this a typical self-help book. To me, it’s more of a life hack manual—a guide to navigating relationships and boundaries with clarity and confidence. While some of the concepts might seem intuitive at first glance, the way Mel Robbins presents them is eye-opening. Her insights helped me see both personal and professional relationships in a completely new light.The “Let Them” mindset is simple but powerful. It’s about letting people be who they are and focusing on what you can control—your own reactions, energy, and peace. It’s a shift that feels both freeing and empowering.If you’re someone who struggles with people-pleasing, overthinking, or just wants to feel more grounded in your day-to-day interactions, this book is a game-changer.

It WILL help, if you let it!

Game changer. If you're open minded and want to change your thought pattern, this will 100% do it. It's real life. It's honest. It hits home on a bazillion things we all go through in life. It's completely helped me navigate some tough things I'm dealing with and it's so simple. My husband hasn't read it but he's heard me talk about it and watched me practice it and now HE's saying, "let them". If it can redirect HIS thoughts, it will for anyone! Read it! Buy it for your friends and family! Maybe the world will be a nicer place if we could all practice this!

The Let Them Theory by Amy Weatherly – A Simple, Powerful Mindset Shift

The Let Them Theory isn’t your typical self-help book—and that’s exactly why it works. Amy Weatherly takes a simple concept—“let them”—and turns it into a transformative way to handle relationships, boundaries, and inner peace.What stood out: • Practical wisdom, not preachy advice: The central idea is this: if people want to judge you, exclude you, or behave in a way that doesn’t align with your values… let them. You stop chasing, over-explaining, or managing everyone else’s expectations. It sounds basic, but Weatherly explains it in such a freeing, empowering way that it really sinks in. • Relatable tone: Her writing is like hearing a friend talk you down from a spiral. It’s warm, conversational, and rooted in real-life examples. No fluff, no jargon. • Permission to stop over-functioning: This book gives you mental clarity when you’re stuck trying to “fix” relationships or gain approval from people who aren’t really for you. It’s a great reminder that peace is better than control.Who it’s for:If you’re a people-pleaser, struggle with boundaries, or are constantly second-guessing yourself in relationships (romantic, family, work, or friendships), this book will speak to you. It’s a quick, encouraging read—but one that stays with you.Bottom line:The Let Them Theory is one of those books that feels like a breath of fresh air. It’s not about giving up—it’s about letting go of what you were never meant to carry. Highly recommend if you’re ready for a mindset shift that actually lasts.

A worthy self-help book

Not a fan of self-help books, I debated buying one which would surely be a waste of money and time again. However, after hearing much buzz about this one being on every bestseller list and a top book club pick, I gave in. Maybe it would be worthy of my time. It mostly was, and now I find myself saying about different situations, “Let them.” That mind set does help me keep from wasting energy on what I can’t control, comparing myself to other people, and overthinking. The chapters I liked best helped me to understand how friendship groups change through the years, and if I feel left out, it could be my fault. Since I’m married, I mostly ignored the chapters on how to improve one’s dating life. The book is divided into two parts: Let Them and Let Me. I found value in both, surprising myself by reading to the very end. Parts of the book are repetitive, but maybe when we are learning new ways to think or act, redundancy will help it sink in.

Mel’s Search for Meaning

The book is good. The chapter on dating and relationships is in my opinion the best. This book certainly has a lot of Meditations vibes. Also, if you want something similar but with more depth then Man’s Search for Meaning by Victor Frankyl is where you should look. That book is fantastic, not to over shadow this one. The book makes some good points I just don’t know how much I trust the “Let them” phrase in every paragraph. Starts to feel like a sales pitch. Nevertheless, it does have an impact on your perception of the world and can change your life in a positive way. This book is definitely worth a read so give it a shot.
