When I started high-fiving myself in the mirror, the effect was beyond my imagination.
By itself, self-criticism and self-loathing disappeared.
It changed the way I look at my life.
High five is the starting point of a great transformation in my life and the dividing line that divides my life.
It is also an opportunity to start a completely new relationship with the most important person in my life, myself.
The way I look at myself and what I can do has changed.
It led me to invent a whole new way of experiencing life.
That's why I wrote this book.
---「Chapter 1.
From "The Discovery of a Lifetime, High Five"

You don't need to change anything.
You just have to accept yourself.
If you ever stand in front of a mirror in the future, don't dig into your shortcomings one by one.
You will only end up feeling defeated, rejected, and frustrated.
And that feeling dictates what you think and how you feel throughout the day.
Instead, why not start each morning by finding something in yourself that you're grateful for?
(…) You may be dissatisfied with your current life.
Despite all the hardships, you have come this far.
Still standing here with resilience and strength.
Waking up every morning and pushing myself to learn, grow, and become a better person.
Honestly, that looks really cool.
---「Chapter 3.
From "The person who hates me the most in the world"

We all make mistakes.
The worst things that have happened to you will be your best teachers.
You need to stop berating yourself and learn from your mistakes.
Although it may seem simple, it is not an easy task.
The most difficult thing is to shift your focus from the past to the future.
It's important to remember that your windshield is larger than your rearview mirror for a reason.
You must not go back.
You have to look 'forward'.
I believe that there are always second chances in life.
That moment every morning when you look in the mirror and decide what kind of person you want to be today is that opportunity.
You have a choice.
You can't turn back time, but you can use the time you have control over to change your actions and create a new life.
So, let's take a look at my past life, which was unrecognizably different from now.
I'd like to tell you about the most difficult time in my life.
---「Chapter 4.
Nevertheless, we must look ahead and move forward"

I wanted other people's success to be my success.
I thought it was too late for me to follow in their footsteps and achieve success since they had already achieved all the success.
I felt like I had no choice but to admit my inferiority complex.
At some point in our lives, we all feel like the life we ​​dreamed of has been stolen from us.
Because someone else has already accomplished it.
Because of that, we give up on ourselves.
Jealousy usually breeds negative emotions.
But jealousy is also a measure of your ability to achieve something you desire.
---「Chapter 7.
From "Why does other people's life seem easy?"

You have the power to achieve what you want.
Of course, it's up to you whether you achieve it.
You always come up with a million excuses not to do it.
The most important thing in life is action.
The more consistently you take action on something, the more you will believe in yourself.
Because through your actions you will perfectly prove that you are not someone who sits still and feels worthless.
There is no perfect timing, perfect plan, or perfect moment.
Now is the best time.
Time keeps flowing.
You are responsible for your dreams.
There is no one who will come to make your dreams come true for you.
If you want a new future, act accordingly.
No matter how scared you are, just start.
---「Chapter 9.
From “Everything requires a deadline”

The reason you are anxious is because you don't know who you should be.
You constantly monitor the atmosphere around you to determine how to act.
He doubts his every action.
Women in particular often suffer from this type of anxiety.
Women are forced by society to play certain roles.
You have to play the role of a good daughter, a good sister, a good student, a good friend, etc.
Always try to please your parents.
You must dress appropriately and not give inappropriate answers during class.
It's natural to worry about whether people like you.
---「Chapter 10.
From “How to break free from other people’s approval and standards”

Life sucks sometimes.
When you feel like you can't seize an opportunity no matter how hard you try, just keep doing what you're doing.
Cry your heart out, get up, and go for your desired goal.
If you give up, you are giving up on yourself.
You have to keep moving forward, telling yourself that something great is coming.
I did the same thing in difficult times.
This can be seen as a mental high-five to yourself.
Reassure yourself every day that your hard work will be rewarded someday.
All you have to do is be patient and keep going.
Then, one day, the results will be revealed.
---「Chapter 11.
From “Why Do I Ruin Everything?”

Dreams don't disappear.
You were born with a dream and that is your destiny.
Wherever you go and however you change, your dream will be with you.
So stop running away and embrace it.
See, hear, and feel all the clues life gives you.
Believe that wherever your dreams take you, you can confidently walk that path.
I am still by your side.
Remember I'm cheering you on with a high five.
You can do it.
My friend, I believe in you.
Now it's time to believe in yourself and make your dreams come true.
