Forgetting after reading is not because of your poor memory: turn every book into an "output note" for action
In many people’s homes, there is a row of books on the bookshelf. The spines are straight and neatly arranged, but the inner pages are as clean as if no one has ever turned them. But it’s not that they haven’t been read—on the contrary, every one of them has probably been read carefully. The problem is, after reading them, they quietly return to the shelf, taking with them what I thought I learned.
A few months later, someone would ask about one of these books, and they would probably only be able to answer the title of the book, a line of text in the middle of the book, and a vague impression of “I think I’ve read it, and it seems to make sense.” As for those passages in the book that made me nod my head immediately? I don’t know where it went.
For a long time, everyone would blame this on memory. Until I discovered that the problem was never memory.
You either didn’t read enough or you only did half of it.
We have a deep misunderstanding about reading: we think that learning is complete when we see the words in our eyes and read the book to the last page.
But that’s only half. Reading is “input”, putting other people’s thoughts into your head; but what will really change you is “output” - you turn what you read into something you can say and do. If a key point is not followed by an action that you will actually do, it will just be a good saying that stays in your mind. After a few days, it will naturally evaporate.
To put it more bluntly: Reading without taking action is almost the same as not reading at all.
This is why some people read three books a year, but they are obviously growing up; some people read fifty books a year, know a little about everything, but their lives remain the same year after year. The difference is not in how many books they have read, but in how much they have read and actually turned them into done. I talked about something similar in “AI Learning and Application Action Guide”: The end of learning is not knowing, but being able to use it.
Exporting Notes: Four Steps to Make a Book Really Stay
So how do you turn input into output? I really like a simple method in the Japanese speed reading school called outputting notes. It’s not fancy, just four steps, but each step forces you to move from reading to doing it.
The first step is to write down the purpose of reading. Before opening the book, explain clearly in one sentence “Why I read this book.” Do you want to improve communication with your supervisor, or do you want to understand how to use AI to create content? With this step alone, your eyes will automatically filter, read faster, and catch more important points that are useful to you.
The second step is to write down the title of the book, the date and how much time you spent reading it. It may seem like just a running list, but writing down your reading time will bring you a small sense of accomplishment and make reading easier to develop into a habit. This is the same thing as what I have been talking about “Build your own reading ritual” - make the behavior traceable and it will last.
The third step is to condense the essence of the book into less than 20 words, one by one. Note, it is within 20 words. This restriction is critical: it forces you not to copy the original text, but to really digest it and speak it once in your own words. You will find that whether you can squeeze an important point into 20 words is whether you can understand its lie detector. This step is also the “Are you writing notes, or are the notes writing about you?” ](/blog/are-you-writing-notes-or-are)》I would like to remind you: No matter how neatly you copy your notes, they are not yours.
The fourth step is also the most valuable step of the entire method - attach a specific action to each essence.
The essence of “Common sense will change with the times”, the next action can be: when doing planning this week, first think of three ideas from a counter-common sense perspective. “Excessive concern will turn into nosy.” The next step is to deliberately keep a distance from a colleague’s project. The essence is the truth you read, and the action is the little thing you will do next week. When every truth grows a foot, reading truly comes to fruition.
A number reveals the truth about your study
After completing these four steps, you will get something very honest.
You read a few gems (this is the input), and a few of them are actually followed by action (this is the output). Comparing the two, there is a number that you cannot fool yourself - your “output conversion rate”.
After reading ten essential articles, only two actions were taken, and the conversion rate was 20%. The eight articles that were not followed by action are the readings that you have not yet fulfilled. It changes the vague self-feeling of “I have read a lot of books” into a clear question: So, how many things have you done?
I like this very much. Because it doesn’t talk about big things, it just quietly spreads the transcript in front of you. This is consistent with my proposition in “Smart Use of AI, Big Functional Upgrade”: What really widens the gap is never how much input you have, but what system you have established to turn input into output.
I made it into a tool: output note taker
I understand the truth, but there still needs to be a place to start. So I made a free little tool in my AI lab called Output Note Taker.
It will take you through the four steps above: fill in the purpose of reading, write down the title of the book, condense the essence into 20 words one by one (if you exceed it, the number of words will turn red by itself, reminding you to wring it out again), and then add an action to each essence. As you fill in, the output conversion rate at the top of the screen will jump instantly, telling you how much of what has been read has been turned into done work so far.
After filling it out, it will generate a clean output note card for you, which can be saved as a picture card and posted to the community, or downloaded as Markdown or PDF and included in your note library. Finally, there is a prompt that can be directly pasted into ChatGPT or Claude. It is an AI output coach: it will check whether your essence is really digested or copied, change the actions you wrote that are too vague to be more specific and executable, and then fill in the essence that has not been connected to actions one by one. Of course, the decision whether to do it or not and which one to do first is still in your hands.

Finishing reading is the starting point, not the end.
Our generation never lacks information. There are so many books, articles, podcasts, and online courses that I can’t finish them in a lifetime. What is really scarce is the ability to turn what you read into something that actually grows on you.
Typing out notes doesn’t make you read more, it makes you read more efficiently. For the next book, don’t just close it after reading it. Try to write an output note for it. For each essence that touches you, add an action that you will do next week. As you accumulate each book one by one, you will slowly become a person who can tell what you have read and can do it.
And if you want to turn this kind of “turning what you learn into what you do” into a system that will continue to operate - not just for studying, but for your work and career - that is exactly what I will take you to do in solo.tw’s practical courses.
Let’s start with an output note. Finishing reading is never the end, it is where you finally start.
