A magic spell that will completely change my life!
When you shout 'Let Them', everything changes!

I thought that if I worked hard, said the right things, and was kind, I would eventually be recognized, loved, and happy.
But the reality is that no matter how hard you try and humble yourself, someone will still be disappointed in you and someone will never stop criticizing you.
And you think you lack self-effort.
"What's the problem? Why do I always fall into this pattern?"

Mel Robbins, speaker, life coach, and international bestselling author, says he wrote this book to help us stop wasting our energy on other people's opinions, feelings, and actions, and focus on the one thing we can control: ourselves.
That is ourselves.


Let's give up, or 'let go', is not about giving up power, but about taking it back.
We can't control what others feel or think, and we can't control the roller coaster ride of our emotions, but by choosing how we respond, we gain power over ourselves.
Letting go is like kicking off the ground and climbing up on a seesaw instead of letting the weight of negative emotions weigh you down.
No matter what anyone says or does, it is the other person's choice and I am not swayed by it.


For example, the author says that you shouldn't be upset because your friends went out to play without you, or you shouldn't be anxious about what you did wrong.
“If my friends go out for brunch or travel without me, that’s their choice.
It's not like there's a conspiracy to exclude me, and even if there is, let's just leave it alone." This is a way of detaching emotions.

Or let's say you presented an interesting idea during a meeting.
The attendees nodded politely, and soon someone else's idea was gaining attention.
I feel like I've become invisible, I regret not speaking more clearly, and I lose confidence.
But let's take a moment to catch our breath and say, 'Let's just leave it alone.'
Let's leave it alone even if it's not adopted.
Their reactions don't change the value of your idea.
It doesn't change your values.


The only thing I can control is myself!
Leave them alone and let me do it!

Let's leave it alone theory isn't all about 'letting it alone'.
You must create the life, relationships, and connections you want by practicing the second important step: Let Me.
In other words, rather than stopping at not caring about others, I should take action that is necessary for me.
For example:

· I'm on a plane, and the man behind me keeps coughing?
- I let myself cough + I wear earphones and a mask to protect my health.

· I haven't been to any gatherings for a while, and now my friends are gossiping about me behind my back?
- Let me swear + I make new, better friends.

· Even though your performance exceeded expectations, your company did not promote you?
- Let the company evaluate me that way + I update my resume and get a better job.

The author decided to share the usefulness of the Let's Them Theory, which he discovered by chance on the day of his son's high school graduation party.
So I posted a 60-second video explaining this theory on social media.
In just one day, it was viewed by 15 million people and received tens of thousands of comments.
News outlets began writing about the theory's effectiveness, people from all over the world sent DMs and emails with their stories, and psychologists analyzed the phenomenon on blogs.
Encouraged by the immediate response, the author recorded his experience using the Let's Make Them theory as a podcast episode.
It was named one of the 'Most Shared Podcast Episodes Worldwide' by Apple, and social media was flooded with 'Let Them' tattoo certification shots!

In this book, the author draws on his own personal experiences as well as research from psychology, neuroscience, ancient philosophy, and relationship experts to explain the remarkable power of Lethem Theory, and encourages you to apply it to eight key areas of your life where its impact will be most immediate and positive.
Only when you let go of your obsession with other people's thoughts, words, and actions will you have the energy to focus on your own life.
I stop living a life reacting to others and start living my true life.
This book, which helps anyone achieve a truly "chill" life in a way that is easy to implement, will clearly show you what kind of fulfillment you can experience in life when you focus on yourself rather than others.


“The more you let them live their lives, the better your life will be.” ― From the text

Bringing freedom to life and simplicity to relationships
The art of healthy balance and boundary setting!

However, the Let's Them theory does not imply indifference or abandonment of others.
Because this is a story about balance, not superiority.
It's about giving others the freedom to do what they want, to live their own lives, and to do the same for yourself.
So the second half of the book analyzes how to deal with the subtle dynamics seen in adult human relationships.
Whether it's friends, family, lovers, or neighbors, human relationships become more satisfying when we accept each other as they are and stop trying to force change.
Because relationships are built on trust, acceptance, and authenticity.
To this end, the author introduces the 'ABC Loop', a conversation formula that brings about change, and the '5 Whys Technique', which helps people discover the root cause of their inability to escape from a problem.

The Let's Them theory can also be applied to children and team members.
The appendix provides guides for parents and team leaders, each written in collaboration with experts in child education and leadership.
It's never too late to make peace with yourself, find good friends, strengthen family ties, and achieve the love you've always dreamed of.
Here are some of the benefits we can gain by putting the Let's Theme into practice:

· You will have more time to take care of yourself.
Because I realized that many of the issues I had been worrying about weren't worth my time or attention, and that I didn't need to waste my energy on people who didn't matter.

· I can see my emotions more clearly.
I become more aware of exactly what is influencing my emotions.
This helps me control my emotions.
· Can be flexible.
You become less fixated on specific outcomes and more able to adapt to changing situations.
This can increase resilience and foster an open perspective on life.
· Beneficial for mental health.
Trying to control everything leads to burnout and frustration, but Let's Do It reduces emotional exhaustion and mental fatigue and enables healthier thinking.
· You can live a more fulfilling life.
By giving more mental space to your needs, desires, and interests, you can regain satisfaction and control over your life.
· You can create healthy human relationships.
By not trying to fix or change them, you allow them to be fully themselves.

For those of you who have been swayed by the emotions and expectations of others and have been mentally exhausted from worrying about and managing the people and situations around you, "Let Them Theory" offers a very simple and refreshing solution.
Detaching ourselves from uncontrollable outcomes, balancing the tilted seesaw, and living a truly free life.
It all starts with this one word.
'Let's leave it alone.'
