To those who are grateful

“The reason life is so turbulent is because of you, not them!”
Are we going to continue to be manipulated by 'idiots'?
Or will you start changing right now?

Since humans are social animals, they cannot live alone.
Whether we like it or not, we interact and build relationships with all kinds of people.
When you meet different people, it is common for both good and bad things to happen.
No, let me be more honest.
Everyone has thought at least once, 'Is this a curse?'
Sometimes I think, 'Why are there so many weird people around me?'
Even on the subway on the way to work.
Even at a cafe.
At work too.
Especially in broadcast programs and online communities.
We often encounter people who are in charge of 'him' in 'Why is he like that?'
Energy vampires, habitual liars, and over-the-top rappers add to the already burdensome daily life.

Author Lee Min-gyu described them as 'idiots', and our lives are a process of struggling to survive among such 'idiots'.
And sometimes I look at them as if I'm doing a mid-check and make a promise.

'I should never live like that.' But let's think about it.
Have you truly made any "efforts" beyond "pledges" to live a better life than theirs? Perhaps you've been consoling yourself by only seeing the flaws of those problematic people and telling yourself, "I'm better than them."
There is no progress without change.
Just judging others from your seat only reinforces a loser's mindset.

Author Lee Min-gyu firmly tells us to remember this.
“If you want to live a different life from them, you must change yourself.
“You must brutally kill your foolish past self and be reborn.” And through this book, “Kill and Be Reborn,” I intend to share practical secrets and know-how to live differently from them.

A life changer sought out and followed by 20,000 people a day
A life mentor who changed the lives of 1,400 people
Author Lee Min-gyu's life strategy guide returns in a "Gold Edition."

This book is not just a collection of empty promises, but a collection of practical strategies that can bring about real change.
The book is broadly divided into two topics.

Chapter 1, “Human Relations,” provides tips for communicating comfortably and smoothly with others.
I've compiled the data I've gathered through trial and error in detail, so you'll be able to gain a certain level of experience with a minimal investment of reading.

Chapter 2, “Mindset,” covers how to maintain a positive mindset and the virtues and habits that make you an attractive person.
Even if you have accumulated experience in interpersonal relationships, it is difficult to maintain relationships without substance.
That is why it is most important to improve the bad habits and ways of thinking that are built into me.
The 'Mindset' chapter describes specific methods for changing attitudes and habits in an easy-to-follow manner that anyone can follow.
It is based on the author's own experience of escaping from a dark tunnel, so if you just follow it, you can save years and become a better person much faster.

The author says that he had a childhood that was far from happy.
Diagnosed with childhood depression at age 10, he spent the next 11 years battling the illness.
But now, his weak heart is nowhere to be found, and he has become a young man with a stronger heart and mentality than anyone else.
As a life changer, I am helping tens of thousands of people fundamentally redesign their lives.
Advice based on an experience that completely turned my life upside down.
Life satisfaction has also increased significantly.

His secret to bringing about this change is simple: 'concentrate all your energy on changing yourself, not others.'
Now, author Lee Min-gyu wants to share with readers the strategy that completely turned his life around.
"Kill and Be Reborn" is a complete guide to life, filled with proverbs, psychology, the core of brain science theory, and the practical experiences and know-how that created present-day happiness.

The title might sound a bit provocative to some.
But changing your life means taking the effort to eliminate yourself.
Rather than criticizing others and frowning at not being able to understand them, the title is derived from the author's realization that "change" occurs when you completely change your existing perception and way of thinking, when you let go of your past "self" and are reborn anew.
It will be a difficult journey, but the rewards will be well worth your efforts.
It's as if the writer's life has completely changed.

Here's what readers of this book will gain:
How to set boundaries that are respected without being kind, conversation skills that let you say what you want to say but not cross the line, the mindset that will increase your life satisfaction by 200%, the best way to get revenge on someone who ignored you, and even the secret to the "winner's mindset" that only successful people possess.

I hope I don't waste any more of my precious time and energy on them.
Readers of this book will gain the fundamentals to truly live a different, better life, rather than just empty promises like, "I won't live like them."
I hope that these secrets, which completely transformed the writer's life, will also revolutionize the lives of readers.
