“If a dwarf stands on the shoulders of a giant, he can see further than the giant.” The record is the same.
Even though I am a dwarf now, if we accumulate daily records, we can see further and think more deeply.
Using the records I have left as a stepping stone, I will be able to face myself as a giant who stands at the highest place.

---From the introductory text, “Writing Shows the Direction of Life”

If studying, reading, or attending lectures is merely a passive act, then you are not really learning or reading properly.
In order to connect with growth, you must go through the process of ‘thinking.’
Do you ever find yourself reading a book and thinking, "What was I reading so far?" or listening to a lecture and thinking, "What's the point of this person's words?" If you don't, you're studying very inefficiently.

---From Chapter 1, “Growth”

The core of records, which the academic field of archival studies has long understood, is simple.
If 100 records are created, only the important 10 are kept.
Selecting the most useful records and utilizing them is called 'appraising and selecting'.
That is, evaluate whether the records are valuable and then choose which records to continue using.
This is also the most important area in archival studies.
So, we can say that the person who records is the person who selects 10 valuable records out of 100.
Discovering shining jewels among countless elements like grains of sand.
This is an important skill that we must develop throughout our lives, regardless of field.

---From Chapter 3, “Concentration”

When you face a difficult problem in life, simply knowing how to sort through the many pieces can provide a clue to solving the problem.
It's a really simple method.
All we need is to activate the dormant fragments of thought.
Keep this in mind.
The answer to my worries already lies within me.
Again, categorizing and recording your concerns is the easiest and fastest way to find answers to your concerns.
All you need is some time alone to think calmly, some paper, and a pen.

---From Chapter 4, “Expansion”

A conversation record is not a verbatim transcription of the entire content.
It's closer to writing down the context of the conversation based on keywords.
It's enough to be able to recall what conversations you had later when you look back.
(Omitted) People who write down the entire conversation like a stenographer are bound to miss the usefulness and essence of the conversation, just like people who don't write it down at all.
If you're going to write everything down, it might be better to ask the other person for their understanding and record it.
Keep this in mind.
The reason we record conversations is not to submit them as evidence to a court.
The purpose is to understand the information heard in the conversation and then extract only what is necessary to turn it into knowledge.

---From Chapter 6, “Dialogue”

There are records of countless geniuses who left their mark on history, but the best individual record is the classic of classics, Admiral Yi Sun-sin's 『Nanjung Ilgi』.
『Nanjung Ilgi』 contains the essence of the records I would like to recommend to you.
He was a master of records, synthesizing the various skills necessary for life into a diary.
He kept a diary for seven years, from 1592, when the Imjin War broke out, to 1598, when the second war ended.
The principle of record-keeping that proper records can only be kept if they are kept consistently has been practiced for over 430 years.

---From Chapter 7, “Thoughts”

The ultimate purpose of using a planner is to visualize my day.
It's about thinking about things you haven't done yet.
When I imagine myself, it means that I constantly think about and meet myself.
This also helps me a lot in living my true self, which I emphasized earlier.
Let's make sure to take care of the two things I introduced earlier: the core of my life (dream) and the core of today (schedule) every morning.
I'm so used to this routine that I feel uncomfortable if I don't start my day with a journal.
Planning my day allows me to welcome the time given to me with joy and positivity.
Of course, there are days when nothing goes according to plan.
But you can try again the next day.
A new day always comes.
A person who has established a routine of recording is not easily shaken.
---From Chapter 8, “Daily Life”

I bought a notebook with a little over 200 pages and started writing in one volume every month.
I wrote my plan on the left side of the notebook and recorded my execution on the right side.
When I woke up in the morning, I wrote down everything I had to do that day on the left side, and on the right side, I wrote down everything, such as what I studied from what time to what time, and who I met from what time to what time.
And at the end of the day, I wrote down my evaluation of the day, my resolutions, and my compliments.
I also wrote down what I studied, and when I summarized what I studied, it came to about 5-6 pages a day.
After repeating this, at some point I started to feel like I hadn't studied enough that day if I didn't write 5 or 6 pages.
