Dale Carnegie's greatest masterpiece, paired with "How to Win Friends and Influence People"
A must-read before worry ruins your life!

The core principles of a worry-free life, as personally applied by Warren Buffett.
The magic formula born from the world's first 'worry overcoming laboratory'!

Following Dale Carnegie's "How to Win Friends and Influence People," which became an instant bestseller, Hyundai Intelligence published another masterpiece by the author, "Dale Carnegie's Self-Management."
This book is the only complete translation of the original first edition in Korea, containing all 10 parts of the 1948 first edition.


A beautiful old tree that has withstood countless storms and lightning strikes falls helplessly after being attacked by a beetle the size of a human finger joint.
An elephant, whose fighting prowess is so strong that even a lion cannot attack it, is helpless against the thin sting of a honeybee.
Our lives are no different.
As the saying goes, “A single ant hole can destroy a great levee,” there are many people who ruin their lives by easily giving in to petty worries.
Worry doesn't ease tomorrow's sorrows, but rather robs us of the strength to live today. If we allow worry to eat away at our lives, we will pay a heavy price someday.

Dale Carnegie, author of the best-selling book "How to Win Friends and Influence People," realized while teaching adults communication and interpersonal skills that "worry" was the main cause of all life's problems and a key element of self-management.
So I decided to teach 'How to Stop Worrying and Start a New Life'.
But a problem arose.
I couldn't find a book suitable to use as a textbook.
In the end, I had no choice but to write it myself.
This is the background to the birth of another world-class bestseller.


He combed through all kinds of materials from East and West, past and present, and sought advice from experts in each field.
Moreover, by using the lectures held in over 170 cities as a 'worry overcoming laboratory', we collected and analyzed numerous cases and came up with a 'magic formula'.
Written over a period of seven years, including preparation, this book contains all the wisdom you need to shake off your worries, presented concisely and clearly.
It also presents concrete solutions that can be applied immediately, along with vivid examples from celebrities and ordinary neighbors from all walks of life.
These are all methods that have proven effective over a century since the early 20th century when he was active.


This book, which contains the most practical and effective methods to live without worry, is considered a classic self-help book along with Carnegie's other masterpiece, How to Win Friends and Influence People.
If you dream of a happier life beyond your current self, listen to Carnegie's advice, which will awaken you from your lethargic daily life and lead you on the path to change by pinpointing the core.


“I learned the most important thing in life from Dale Carnegie.” _Warren Buffett

I worked in the 'Worry Overcoming Lab' for five years.
This is my class time for adults.
As far as I know, this is the world's first laboratory built for this purpose.
We gave students some strategies for overcoming anxiety, asked them to apply them to their own lives, and then presented their findings to the class.
Some students shared methods they had used before.
Through this process, I am proud to say that I have heard more 'how to overcome worry' than anyone else in the world.
We also encountered hundreds of case studies selected from classes held in over 170 cities across the United States and Canada.
Therefore, this book was not created in the ivory tower of a university.
This isn't an academic sermon on how to overcome anxiety.
It's a concise and compelling account of how thousands of adults overcame their worries.
As an author, I can be proud of one thing.
This book is concrete and reliable.

From a psychological perspective, what makes Willis Carrier's magic formula so brilliant and practical? It's because it pulls us out of situations where worry, like a thick fog, blinds us and renders us unable to see anything.
The way he writes makes you stand firmly on the ground and face your situation.
Wouldn't it be impossible to think properly if you don't know the situation and the basis? (...)
Psychologically, accepting the worst releases new energy.
If you accept the worst, you have nothing to lose.
Then only what you can get remains.
(…) Many people ruin their own lives in the whirlwind of anger.
They refuse to accept the worst, assume the worst and then try to improve it, and they don't even try to salvage what they can from the wreckage.
Instead of trying to rebuild their lives, they become filled with resentment and engage in 'worst experiences and fierce fights'.
In the end, you become a victim of depression, where your thoughts are fixed and you do not take any action.

Through many experiences, I have learned how important it is to make decisions.
If you can't reach your goals and keep going around in circles, not taking a single step forward, you'll end up with a nervous breakdown and a hellish life.
I've found that the moment I make a clear and firm decision, 50 percent of my worries disappear.
40 percent of decisions disappear when you put them into action.
Ultimately, I was able to eliminate 90 percent of my worries by following these four steps:
1.
I'll write down exactly what I'm worried about.
2.
I write down what I can do.
3.
Decide what to do.
4.
Execute immediately as decided.

Most people find it easy to get 'engaged' when they're working hard or doing something assigned to them.
But the time after work is dangerous.
In our free time, when we should be enjoying our leisure time, the time when we should be most happy, a dark demon called worry attacks us.
That's when we start to worry about whether we're living well, whether we're just going around in circles without any progress, whether what our boss said today meant 'something', or whether we're going to go bald.
(…)
Even an empty mind can be filled.
What will it be filled with? Usually, it's emotions.
Because emotions like worry, fear, disgust, jealousy, and envy arise from primordial vitality and dynamic energy.
Negative emotions crowd out peaceful and happy thoughts and feelings from our minds.

The more influential someone is, the more satisfaction those who kick them away feel.
Edward VIII, now the Duke of Windsor, felt this painfully during his time as crown prince.
He attended Dartmouth College in Devonshire, the equivalent of the Naval Academy in Annapolis in the United States.
At that time, the crown prince was about fourteen years old.
One day, a naval officer saw the crown prince crying and asked what was wrong.
The crown prince initially kept his mouth shut, but eventually he confessed the whole story.
The cadets kicked him.
The university dean called the students in and explained that the crown prince had not been the one who had tatted, and then asked why they had chosen the crown prince to harass them.
The cadets, who had been hesitating and faltering for a long time, finally confessed.
It is said that later, after becoming a commander or captain in the British Navy, he wanted to brag about having kicked the king in the past.
When you get hit or criticized, remember that the abuser does it to feel like he or she is a great person.
Such cases usually prove that you have done something great or are someone who deserves attention.

There is a surprising and important fact.
People don't get tired from mental work alone.
Sounds far-fetched, doesn't it? But a few years ago, scientists studied how long the human brain could work without reaching the scientific definition of fatigue—"a decline in working capacity." Surprisingly, they discovered that the blood flowing through the brain during exercise showed no signs of fatigue.
If we take blood from a vein while a day laborer is working, it will be full of 'fatigue toxins' and fatigue substances.
But if you took a drop of blood from Albert Einstein's brain and examined it after a long day, you would find no trace of fatigue toxins.

Our brains work just as fast after eight or even twelve hours of work as they did at the beginning.
The brain doesn't get tired.
Then why are you tired?

My 15-minute conversation with Professor Baird did more for my health and happiness than my four years of college combined.
He said this:
“Jim, sit down and face the facts.
If you could devote half the energy you spend worrying to solving the problem, your worries would disappear.
“Worry is nothing more than a bad habit that is learned later in life.”
He taught me three rules to break the habit of worrying.
1.
Identify exactly what the problem is.
2.
Identify the cause of the problem.
3.
Do something constructive to solve the problem right now.
