Description
Book Introduction
“Those who spend their time differently end up living differently.”
The moment when time accumulated at your own pace changes your life
The Mystery of the Century: One person is a lawyer representing a law firm, a writer, a working mother of two, an Instagram cartoonist, and a writer for the drama "Good Partner." Is that even possible?
This is a comment below the video featuring attorney Choi Yu-na.
This is also a list of what attorney/writer Choi Yu-na is actually doing right now.
What kind of life has author Choi Yu-na, who lives a life that is considered a great mystery to most people, lived?
The author describes himself as someone who was born with a weak body and often gets sick, someone who has a complex about his lack of perseverance, someone who majored in English but failed, and someone who cried for days because he came last in the local law school he entered based on his grades.
He also confesses that he was an average person who did well in school but was not particularly outstanding.
However, he had a dream of 'wanting to help others', and thanks to that, he spent each day fiercely worrying about various things.
Thanks to my desire to improve my main job as a lawyer, and the challenges I took on in various fields, and the fact that I achieved near-success in most of them, I decided to write my first self-help book, which teaches that "ordinary people can do anything."
The most important cheat key to his achievements is 'mileage hours', a method of accumulating time little by little like airline mileage.
To do that, you need to change the way you think about time, create a routine, change your mindset, and start right now.
If you read this book and follow the author's lead, slowly and steadily, you will find yourself one step closer to living the life you have always dreamed of.

Into the book
'I'm saving for the future now.
Invest your time in growth with the mindset that 'this will compound interest later'.
Eventually, you'll need less and less of that time for recovery, which is the first part of your time divided into three parts, and you might be quite satisfied with just splitting it into two parts for your current work and growth.
Ultimately, the reason I need time to recover is most likely because the stress I feel stems from the feeling that I am not living for a better future.
I sincerely hope that you will live a life where you can create and enjoy time without being caught up in time.
--- p.42, from “Divide 24 hours into three parts”
If you're thinking, "Hey, what can I do with just one hour a day?" or "That person must be lucky or have exceptional abilities," you need to recognize that you are your own biggest obstacle.
Try building a wall with the me who keeps interrupting you and becoming closer to the me who keeps dreaming new dreams in my head, and work on a project together for just one hour a day.
--- p.85, from “Mileage Hour, a small but sure way to change your life”
The way I'm going to tell you is to set aside just one hour a day to invest in yourself.
All you have to do is invest an hour in something you absolutely want to do (painting, traveling, vocal lessons…), something your genes tell you you should do (writing, exercising…), something you vaguely feel will bring you money in the future (YouTube, Reels…), or something you feel is necessary to get better at what you’re doing now (studying a foreign language, taking a coding class…).
--- p.155, from “I am the creator”
If you have a goal in mind and can't take a vacation this year, don't compare yourself to others and lament.
If you get the opportunity you want, you have to stop looking around and thinking, 'Am I doing the right thing?'
Only those who realize that the moment they try to do everything and have everything, what they want is further away, can paradoxically achieve what they want.
This is the most important part of mental management.
--- p.189, from “Accept that you can’t do everything you want to do”
Using mealtimes as healing time is also a way to save time in life.
When we live busy lives, it's easy to miss the people around us.
When I'm eating alone, I sometimes send messages to people I miss, and if I see someone I miss, I suddenly contact them and say, "Can we have dinner together now?"
Of course, if I suddenly call someone over and have a meal with them, I pay for the meal since I save them time.
--- p.289, from “Let’s Love Eating Alone”
From now on, no one will help you.
Growing up is your responsibility.
Change me little by little, slowly, like a parent, by constantly nagging me, disciplining me, and correcting me little by little every day.
Even if you don't know it now, in 5 years, 10 years, you will be much closer to the person you like.

Publisher's Review
“To those who save time, life is given another chance!”
Life Skills of People Who Take the Lead and Achieve Their Goals
“Sir, is this Hermione?”
Hermione, the most studious of the three main characters in "Harry Potter," uses the "Time Turner" to turn back time and attends multiple classes simultaneously, taking all the classes she signs up for.
Hermione and author Choi Yu-na have something in common: they are people who can accomplish seemingly impossible things. However, author Choi Yu-na has a secret weapon she created herself, the 'Mileage Hour', instead of a magical tool given to her by others called the 'Time Turner'.
The author's "Mileage Hour" goes beyond simple time management. It's a high-density life planning guide that introduces the concept of mileage—"accumulating and using time"—to life success, and it's a practical certificate personally proven by the author.
What determines our success is not the conditions we are born with or the innate talents we possess, but rather our proactive attitude and stance toward life. The author emphasizes that we should focus on the present, on the 'me' of today, immerse ourselves in the smallest unit, and persistently accumulate those small growths.
These small, consistent efforts will ultimately lead to overwhelming results that cannot be ignored, taking our lives to another level.
Through this book, readers will learn how to believe in themselves, live as masters of their own time, and regain control of their lives.
Ultimately, through the "Mileage Hour" system, you'll understand how your current efforts can translate into future rewards, and get closer to achieving your dreams.
“The busiest people have the most time.”
Accumulation of time to complete decisive results
In my 20s, I passed the bar exam and heard the news of a family member's terminal cancer.
To overcome my grief, I went to work every day and immersed myself in my work.
I had to start a company in my 30s, get married, get pregnant, give birth, and raise a child.
As soon as I got used to the situation where I couldn't give up work or family, my second pregnancy, birth, and childcare followed.
I had less than 10 minutes of 'my time' a day, so I was busy, angry, and increasingly tired every day, so I had to find a way.
In Chapter 1 of this book, the author suggests a way to shift the way we think about time, moving beyond the excuses of "I'm busy" and the thoughts of "it's too late" or "I'm not ready."
The author's experience of being able to save time by being grateful, especially in the present situation, helps him reflect on himself and face reality clearly.
Chapter 2 introduces the core concept of this book, 'mileage hour'.
It provides specific ways to save time and emphasizes the importance of protecting your own time.
This is followed by practical advice to stop worrying and instead take action, and to make time for rest, even if it means creating a break.
Chapter 3 explains the importance of routine and details how to design your own day.
We encourage you to create and practice routines, build layers of time, and become the creator of your own life, creating consistency.
The comforting thought that there are no perfect people or perfect days in this world eases the burden on our hearts.
Chapter 4 focuses on the mindset that creates high efficiency.
Accepting the reality that even a wealthy tycoon with incalculable wealth and a newborn baby cannot live as they please, the book teaches two mental training methods: how to cultivate the inner self through solitude management and how to avoid being swayed by external forces.
We also share the wisdom that the courage to say no and the power to think positively lead to success.
The last five chapters provide a reminder of the entire content so that you can put 'Mileage Hour' into practice right now.
I want to reaffirm that faith in myself is at the heart of Mileage Hour, and share my experience of writing.
In particular, the last piece of advice, "Become your own parent," resonates deeply with us, who must now discipline and nurture ourselves instead of our parents, who look at us with eyes full of love, nagging us to improve, and quietly watching us grow.
By slowly following this book, readers will experience that a proactive attitude toward time and life and a life attitude transcend talent and circumstances, and will be able to elaborately design the life they desire.
