Let Them is a Great Reminder of What You Already Know
Apart from being full of excellent, freeing advice, this book felt like one big therapy session—in the best way! Mel Robbins gives you tools you may already know but delivers them in a way that feels like permission to truly be yourself. Everything made sense and felt actionable, practical, and doable in everyday life. I even shared it with my daughter before I’d finished reading; she tried to snag it early! The chapter on friendships especially resonated with her. Let Them is a refreshing reminder that it’s okay to let things go, focus on what you can control, and manage your own feelings instead of trying to manage everyone else’s.

A Game-Changer for Protecting Your Peace
The Let Them Theory is such a refreshing and freeing read. It really shifts your mindset and reminds you that you don’t have to control anyone just let people be who they are and move accordingly. The way it’s written is clear, uplifting, and easy to digest, but still hits you with those “wow” moments that make you rethink everything.This book helped me release unnecessary stress and focus on what I can actually control: myself. If you’re on a journey of growth, healing, or protecting your peace, this is definitely a must-read.

NON FICTION IS A GREAT WAY TO LISTEN WHILE YOU DRIVE! TRY AUDIBLE!
LET THEMAUDIBLE NON-FICTION INSPIRATIONAL BOOK ON LISTENING TO MEL ROBBINS MOTIVATIONAL ADVICE MAKES MY DRIVING DESTINATIONS ENJOYABLE! I had something like 24 AUDIBLE CREDITS that have built up because I’m a visual person that loves to read. I’ve had the membership for over ten years and I only like certain NON FICTION SELF DEVELOPMENT books which I listen to Memoirs, Self help, but never fiction books, because my imagination is more vivid when I read. I always either listen to my podcasts on Spotify or NON-FICTION on AUDIBLE which is owned by Amazon. I can’t drive anywhere without my Podcasts or very few Non-Fiction Titles that interest me, but I have had those credits and I love MEL ROBBINS so I decided to try it on AUDIBLE. My friends who read that listen to fiction on AUDIO understood why I bought the same fictional title and I had already loved reading it on my Kindle. It was a favorite lifetime reading experience and I own many of the same KINDLE & AUDIBLE versions but I noticed that fiction book that it was one of the most beautifully written books that when I went to listen to it, I quickly gave up because it was bland. I have been told by more frequent readers like myself who listen to the Audio version and recommend it to me on Audio since they enjoyed it better have said listening to fiction is a skill that you have to develop, so I stick to NON FICTION and I need to listen to something while I’m driving so I buy the Kindle Version & the AUDIBLE and it makes my driving to destinations shorter.v That’s why I have Spotify because there’s two favorite podcasts but I pay extra for no commercials and now my top favorite podcast has commercials which I ‘m considering cancelling because the reason I pay extra is because the commercials drive me crazy so now Spotify says it’s up to the podcast. The reason I’ve been a member since 2018, is because it is synced to the Bluetooth, in my car and the podcasts don’t require Cell towers so you don’t get the buffering that I do with Audible in areas where there aren’t Cell towers which we call them dead zones. I’m recommending this AUDIBLE PURCHASE called, “LET THEM,” because MEL ROBBINS is a new motivational author to me, and she wrote the book which she has some fascinating inspirational content, that I have learned some ideas to improve my life. She is a fantastic narrator in her soothing voice. One nice thing about AUDIBLE is they are extremely friendly and if you don’t like the AUDIO BOOK Listening experience, you can return it, which you can’t do with the KINDLE Books. so I have had to return something only twice in fifteen years, since I usually love what I purchase. I do recommend this book on AUDIBLE to listen to or if you don’t have a membership they used to have a free trial and a free book if you’re a new member. But I’m not sure, but however medium you choose this is a FAVORITE and it’s a bestseller that I can promise you will love it, as well. It has a very high rating of tens of thousands of five star ratings which is even more evident that it’s a Spectacular choice!

Great read!
This was worth the read, some chapters I skipped because I feel like it some point she was giving more of her opinion than she was reasearch. Overall Mel helped me see that I had control issue’s I never noticed I had. In a way this book has helped me to be more forgiving and compassionate towards others especially my in laws lol.I’m satisfied with the book, I’ve recommended it to many family members and I will be reading it again. I feel like this book is a never ending lesson.

Thank you to the author—truly. This book is incredibly important and I wish everyone could read it. Its teachings are powerful, sometimes painful, but essential for personal growth. Every page resonated with me and helped shift my mindset, filling in pieces I didn’t know were missing. I’m deeply grateful this book exists.

The book arrived unsealed, and the cover is dirty — it looks like a second-hand copy.

O livro é realmente incrível, com linguagem fácil e exemplos que nos conectam facilmente com os preceitos da teoria. O único ponto negativo para mim é a capa que é solta e fica caindo toda hora, que realmente não foi uma boa escolha da editora.
