★ The sequel to the popular bestseller, “100-Day Notebook to Fill Yourself with Adult Dignity”!

Adults with a philosophy of life are not shaken by interpersonal relationships!
The dignity of a relationship that maintains a line that is neither too close nor too far

One of the biggest concerns people face in life is the problem of interpersonal relationships.
The relationships surrounding us vary in degree and scope, from the relationships we share with each other every day, such as family, friends, lovers, colleagues, bosses, and juniors, to the social networks formed through social media and various gatherings.
The difficulties in relationships are bound to be different for each person.
Some people worry about why they keep getting hurt by other people, and others worry about having to force themselves into a relationship with someone they just can't communicate with.
Others wonder how to naturally take the lead in relationships while being liked by others.


Although the direction of our concerns may differ depending on our individual circumstances, personality, and age, if we trace back to the starting point, we all ultimately want to maintain our individuality without being swayed by relationships.
For this, more than anything else, a philosophy of life is needed.
An adult with a philosophy of life is not shaken by interpersonal relationships.
A true adult builds relationships wisely, knows how to protect himself within those relationships, and doesn't let problems that arise in those relationships bother him.
To become such a person, we must constantly ask ourselves, "How should I live?" and find the answer.
“100-Day Manual for Cultivating Adult Relationships” is the beginning of that journey.


“To meet a better person, become a better person!”
A 100-day journey to reflect on the essence of deep human relationships.

The desire not to be hurt by others, not to be burdened by others anymore, and not to be swayed by relationships usually leads us to distance and detachment.
The author also says that in order to focus on what is important and valuable, we need to wisely weed out the unnecessary things.
This book is full of valuable wisdom that will serve as a guide for the future, such as what to do when encountering rude people, what mindset to cultivate to avoid wasting your life on others, and how to deal with being constantly conscious of other people's gaze.


But can this truly be said to be the entirety of human relationships? On the one hand, the author points out our biased perspectives and reflects on the intricate nature of human relationships, which we must not overlook.
As emphasized in the book, just as important as getting rid of unnecessary relationships is having a sincere attitude.
"The world returns the sincerity you give it," "Live with the intention of helping others! Then, the number of people who know you will increase, not just the number of people you know!" These are examples of true adult interpersonal skills that encourage goodwill, kindness, and generosity.
Now let's meet the value of sincerity that leads to change in relationships.


The sentences I write become my attitude towards life!
Sentences that help me find myself in a world of others

The author emphasizes that “writing is the process of filling ourselves with the language that contains the souls of others, and through that process, we can learn a broader and deeper affection.”
The author's previous work, "100-Day Handwritten Notes to Fill Up Adult Dignity," was loved by numerous readers because the book provided a time for reflection and allowed readers to reflect on a dignified life.
The author's second 100-day writing collection, "100-Day Writing Collection for Cultivating Adult Relationships," contains sentences that capture the essence of human relationships.


As you transcribe this book, don't just copy the sentences; engrave them in your heart so that they become your attitude toward life.
Whenever I feel shaken in a relationship, handwritten sentences will hold me back.
It will be your compass when you lose your way, and it will quietly comfort you when you are hurt by others.
Now, let's cultivate more diverse interpersonal relationships through sentences that will help me find myself in the world of others.
