"The Let Them Theory" by Mel Robbins Book Review

“The Let Them Theory” by Mel Robbins is one of the most impactful books I’ve read on personal growth and emotional boundaries. This review breaks down the core ideas behind “Let Them” and how it can help you create a more peaceful, confident, and intentional life.

If you're looking for an honest The Let Them Theory book review, this breakdown shares key lessons and real-life takeaways.

I borrowed this book from Kevin because I have struggled for years with worrying about what others think about me, people judging me, and I really wanted to have the peace in my life that I deserved. Mel's theory is this - let adults be adults. Simple, right? So why do we make this action so difficult? 

Reading this book really provided me with a new perspective on my own life by letting adults be adults. That means that adults will make adult choices and you just have to "let them." Yes, it may be hard to watch adults make bad choices - but those are their choices to make - not yours. I've had my fair share of bad decisions and, when you think about it, no one is in control of you, but YOU. 

Is this just an entire book about letting adults make adult decisions? It goes deeper than that. It's about letting adults, specifically, show you who they are. Based on that information, you can determine the next steps on how YOU want to manage your path based on their choices. I took down a lot of notes and a lot of quotes. As I'm also reading the book "Codependent No More" - it aligns very much with this theory of letting someone be who they are and make the choices they want to make. Let them. 

It's harder to live a life of letting adults just be adults. It's easy to stop their path, make choices for them (and I know that family members have been wanting to direct my path as well) and instead allow people to choose who they want to be. You can't change people or force them to align with your expectations - or expectations that we create for them. Instead, let other adults make choices and then we align who we are with that choice. 

We all feel this need to be in control all the time (trust me on this one) but the reality is, no matter what, we cannot control another person. The only person you can control is yourself. 

Have you ever tried to control what a person was doing, saying, feeling, just to prevent the other person from doing something they shouldn't be doing? Has someone ever stopped you from something you wanted to say, feel, or do so that you won't do something you shouldn't be doing? If so, this book is 100% for you.

Mel breaks this book down into different categories and explains how you can use this theory separately. Some categories include: Personal growth, stress, and relationships. This book focuses on emotional boundaries and learning how to release control over others. 

You and The Let Them Theory

Redesign how you live by applying the "Let Them" theory to others - let them make their choice - and the "Let Me" theory of what will you do once they make that choice? Pour your energy into the things that make you happy. By letting yourself determine your path, relationships will improve, you will worry less about the weight of others, and provide yourself with a new freedom. 

Letting them is about releasing yourself from any control you may have:

• Fear of being excluded
• Not being liked
• Things falling apart
• Kids or partners making bad choices

Letting me is about:

• Controlling your own thoughts
• Allowing others to make their own choice
• Accepting reality
• Being more proactive
• Taking responsibility
• Developing better boundaries
• Prioritizing

Free yourself so you can live a more intentional life.

Stress and The Let Them Theory

Stress is a state in your brain that causes tension in your body. Specifically, it can cause:
• Burnout
• Doubt
• Comparison
• Focus
• Constantly tired
• Procrastination

According to Dr. Aditi, "7 out of 10 people are currently living in a chronic state of stress." 

Ways to protect your energy and reduce your stress include:
• Mood
• Mindset
• Health
• Focus
• Disconnect/Unplug

The "Let Me" puts YOU in charge, holds you accountable, and lets you decide. If you start to feel stress, tension, jealousy, anger, or any other emotion that you want to let go of - read this book - and then revisit it when you need it most.

The Let Them Theory and Adult Friendships

Not only are adult friendships hard to find, but they are hard to maintain. Mel speaks about her experience with adult friendships and how she was excluded from friend trips, but also didn't make the effort to get together with her friends in quite some time. It seems like no one has free time, coordinating calendars can feel impossible, and it provides a level of loneliness and isolation that I have definitely felt at times.

Adult friendships require:
• Proximity (being closer to someone is easier to connect and meet with them)
• Time of life/season you are in (you draw closer to people that can relate to you during that time)
• Energy (you either click with someone, or you don't)

Friendships are something you create and connect with:
• Compliment people
• Be curious
• Smile and say hello

Right after I read those - I tried it out at my local market. I smiled, I said hello, and maybe I didn't gain friendships out of it, but I do know everyone that works at the market now. I see them, I say hi, they know who I am, I've received hugs from the cashiers, and even if they don't extend past that, it's still nice to have others around that smile and say hi when they see you. 

As humans, we are social characters and we are influenced by those around us. Surround yourself with people that will bring a light to your life. Someone who will enhance you. And do what you want others to do, model the change you want to see - people will take note. 

Do You Want Someone to Change?

If there is someone in your life that you want to change - whether it has to do with working out, eating less, different hobbies, different friends, Mel provides a strategy of the 5 "Whys" and then the ABCDE method for moving forward. I will share with you the ABC strategy and will leave the rest up to your reading:
A is apologize and ask open-ended questions
B is back off and observe behavior
C is celebrate progress

Remember, you can want someone to change so badly, but until they are ready, and until they want to, nothing will happen. You can push and prowl and claw and do all of the things, but they have to be the one who makes that choice. 

"Helping others doesn't mean doing it for them - it means giving them space, support & tools so they can do it on their own." 

Quotes

Here are a few quotes I appreciated: 

• "All human beings have a hardwired need for control."
• "As an adult, your life, happiness, health, healing, social life, friendships, need, and success, are all your responsibility." 
• "You are capable of creating anything that you want if you are willing to put the time and energy into working for it."
• "We all care what others think. Some people will have negative opinions about you and you can't change that. Let them think what they want."
• "People can only meet you as deeply as they've met themselves." 
• "Most human beings have never done the work to understand themselves, heal their past, or manage their own emotions. If they haven't done that for themselves, they are incapable of doing that for you and showing up in a way that you deserve."
• "Most people don't know how to process their emotions in a healthy way." 
• "Adults are 100 percent responsible for the emotional and physical needs of children. Children cannot give themselves the emotional and physical support that they need. It is your responsibility to help a child regulate their emotions in a healthy way. It is also your responsibility to teach a child that emotions are normal and how to process them." 
• "Emotions rise up in 6 seconds and fall back within 90 if you don't react."
• "You can't let your emotions drive your decisions."
• "The more you try to rescue, the more likely they will continue to drown."

My Story

Reading "The Let Them Theory" reminded me how powerful personal stories can be when someone is willing to share the truth about their life.

Several years ago, I wrote a book about my own experience losing my dad and navigating grief. Writing it was both difficult and healing, and I hope it helps others who may be going through something similar.
