"It's 'life,' not knowledge, that creates true wisdom."

Shigehiko Toyama, a giant of knowledge with 2.5 million readers
Awakening Your Inner Intelligence with Reverse Thinking Lifestyle Habits

★ Amazon Japan's #1 bestseller, "Leap of Thought," practical edition
★ A master of thought respected by Tokyo University students

What does an intellectual life mean? Japanese scholar Shigehiko Toyama, who continued his intellectual creation even at the age of nearly 100, said this.
“Integrate knowledge with life.” 『I Decided to Think While Lying Down』 contains 20 habits that the author has practiced throughout his life, among the ‘intellectual lifestyle habits’ that integrate knowledge into life.

Advice like “If you want to invent, don’t study,” “Lie down and think,” and “Even forgetting is a skill” may seem absurd at first, but the author says that these reverse thinking habits can help you unleash the “power to think for yourself” in real life.
The author emphasizes that the path to true intellectual growth lies in correcting daily habits, one by one, rather than simply acquiring knowledge from the information that pours out every day.

Professor Toyama's most important message to his readers is the hope that we can become wiser as we age.
This book presents habits that anyone can start at any time, opening up the possibility of intellectual growth even to those who think it's "too late."
Professor Toyama has a message for everyone who wants to live an intellectual life until the moment of death.
You can become a more intellectually mature person, wiser tomorrow than you were today.

In today's society, overflowing with knowledge and information, healthy lifestyle habits alone are not enough.
You may suffer from mental overload or stress.
Humans can be reborn through intellectual lifestyle habits, and good intellectual lifestyle habits become a source of mental vitality and enrich life.
In that sense, it has a more important meaning than any lifestyle habit.

In the modern era, which is called the information age, there are so many things that come into our heads that it is incomparable to the past.
There is concern that REM sleep, which occurs naturally, is not enough to eliminate waste, so it may remain in the mind.
How can we forget wisely? This is a challenge for modern people, one that the ancients didn't need to understand.

You shouldn't just keep cramming all the knowledge into your head and digesting it roughly.
The process of forgetting, which involves absorbing and digesting knowledge appropriately and discarding the rest, is as important as remembering.
If forgetting is not sufficient, very dangerous symptoms will appear, not just loss of appetite.
Forgetting must not be neglected.

When you are thinking about something, useless memories only get in the way.
Knowledge and thinking are not on good terms.
As our knowledge increases, we have less need to think and therefore think less.
Necessity is the mother of thought.
If knowledge is enough, there is nothing left to think about, and before you know it, thinking becomes impossible.

At one time, I thought that our daily lives might be like these shabby magazines.
A day spent doing nothing but blankly is like an unedited doujinshi.
There's no way that kind of life would be fun or good for the world.
We must edit our lives.

The less educated one is, the more likely one is to feel the need for new ideas and come up with new ones, but because of a deep inferiority complex, one puts on the brakes.
Intellectuals tend to think that they can handle everything with the knowledge they already have, and in fact, they tend to neglect independent thinking.
In the end, what this means is that ordinary people tend to have the most outstanding thoughts.

A person who doesn't catch a cold or take medicine is like a car speeding down the highway.
You may have forgotten to apply the brakes.
Conversely, a person with a cold is like a car driving on a regular road with many traffic lights.
Even if you try to run, you'll quickly run into a red light, and if you try to run a little, you'll run into another red light, so you won't be able to speed up even if you want to, but there's little risk of an accident.
A car speeding down the highway is at great risk of running a red light.
There is a risk that this could lead to a major accident.
If you think of a cold as a sign of health, you shouldn't neglect it.

Humans have life.
Life is not work, but it is the reality of human existence.
Computers have no life.
Humans are superior to anything else in life.
It is not wise, at least in modern society, to live only for the work that machines can do, as if to disdain that point.
