“I work 4 hours and play 8 hours!”
The Law of 24-Hour Design to Maximize Your Brain's Potential

“Your brain already knows the answer.
“Don’t miss the moment when your concentration explodes!”

We've moved beyond the days of unconditional support and comfort, and now most people need fundamental, scientific solutions.
However, there are still areas that remain stuck in the old ways.
It is 'time'.
While time management tools are evolving, most methods are still stuck in the past, such as waking up early and investing a lot of time.
This is precisely why the 'Best Day Based on Brain Science' routine in 'Brain Science Timetable that Changes Your Life' has become such a hot topic that it has been republished after seven years.
Now, we have entered an era where time management is done scientifically.

Shion Kabasawa, one of Japan's top psychiatrists, has been researching and practicing time management methods based on brain science for many years.
He says that if you schedule high-priority tasks during the peak of your concentration, such as 2-3 hours after waking up, right after taking a break, right before leaving work, or the day before a deadline, the time required will be reduced compared to usual, increasing the usable space of time even within the same amount of time.
What he found was that the times of day when concentration exploded were times when the brain was either energized or completely organized.
Therefore, if you practice increasing the concentration of brain substances needed for each time zone through the methods introduced by the author, such as exercise, changing locations, and meditation, it is possible to reset the brain and welcome the second golden time of concentration.

Ultimately, this book tells us that there is no need to strive for more time or to push ourselves with strong willpower.
Do you want to work less and achieve more? Do you want a life that doesn't tire you out after work? Do you want more time for yourself? If so, what you need most right now isn't a "packed schedule," but a "brain schedule."
Just realizing it and putting it into practice will lead to a life filled with focus and leisure, rather than anxiety and fatigue.

We sacrifice ourselves and our families to focus on our work.
As a result, I become mentally and physically exhausted and cannot work at peak efficiency.
How do you want to work and how do you want to live? Many people believe that "achievement at work" and "enjoying life" are incompatible, but that's definitely not the case.
It was just that work-life balance was impossible because of my wrong way of thinking about time and how I allocated it.
If you cherish yourself and your family first and then devote yourself to your work according to the divine time magic introduced in this book, you will definitely achieve overwhelmingly high results at work.
And that's not all.
You can achieve personal growth and achieve good professional results while also enjoying hobbies and entertainment.
You can also enjoy precious time with your family, lover, or friends.
The ultimate goal of this book is to make you 'enjoy' life.

There are 15, 45, and 90 minute time blocks that you can focus on.
I call these three combined the '15·45·90 Rule'.
Just as waves roll in and out on the beach, our brains also form rhythms based on the highs and lows of concentration.
Rather than going against the rhythm, skillfully riding the rhythm, or in other words, 'surfing the waves of concentration', is the basic way to make the most of your concentration.
The elements of concentration include 'depth of concentration' and 'duration of concentration'.
Attention span varies from person to person.
For someone like me who writes, taking a break every 15 minutes doesn't help my writing speed.
Once you concentrate, you should write continuously for at least 90 minutes.
On the other hand, it is very difficult for people who do simple office work to work for 90 minutes straight.
In such cases, you can handle the work without overdoing it by taking a break every 15 or 30 minutes.
--- From "Chapter 2: The Law of Concentration that Uses 100% of the Brain"

The first 2-3 hours after waking up in the morning are the brain's golden time.
But if I wake up at 7 in the morning, wash up, eat, and leave the house at 8, I arrive at work at 9.
Then, the brain's golden time is only 1 hour left.
If you spend about 30 minutes of that hour responding to emails or messages, your brain's golden time will end without being utilized at all.
Responding to emails or messages is a typical example of a non-focused task that doesn't require much concentration.
What a waste of time it is to do that when you have the most focus of the day.
If you make good use of those 30 minutes of intense concentration, you can handle focused work efficiently.
I start writing as soon as I sit down, and I can produce quite a bit of writing, and quite a high quality piece, in the first 30 minutes.
That's why mornings feel four times more valuable than other times.
30 minutes in the morning is equivalent to 2 hours in the evening.
If you're not sure what to do in the first 30 minutes of work, try to do the most important tasks of the day during that time.
If you use this time well, you can even get off work an hour or two earlier.
It's about finishing difficult tasks that require concentration during the golden time.

2-4 PM is the time of day when I am least productive, as I feel drowsy after eating or fatigue builds up from work.
In fact, if you look at traffic accident statistics, the most drowsy driving accidents occur between 3 and 4 in the morning and between 2 and 4 in the afternoon.
This is also true in overseas statistics.
In other words, 2-4 PM is a time period when biological arousal levels are low and it is easy to become sleepy.
Lowered alertness means lower concentration and work efficiency.
But after 4 o'clock, things change.
The thought, 'I'm almost done with work, so let's finish this quickly!' re-energizes me and my concentration improves.
Therefore, from a time management perspective, it is very important to overcome the time between 2 and 4 PM, when concentration and efficiency tend to decline.
How can we overcome this time of day, when it's easy to become lazy? I'll now introduce the "Afternoon Reset Method."
Please note that this method is not limited to the afternoon.
This is a useful reset method when you feel your concentration is low, so you can use it whenever you are tired in the morning or when you have to work overtime.
--- From "Chapter 4 Day | How to Reset Your Brain in the Afternoon"

The ultimate brain reset technique for doubling your day is none other than exercise.
When you feel tired in the afternoon, doing an hour of aerobic exercise can be surprisingly refreshing for your brain.
You can actually feel your concentration returning, like when you just woke up in the morning.

People who are always saying they are busy and pressed for time are often late for appointments.
Then he makes excuses like, “The previous meeting was long, so I’m late. I’m sorry.”
This is an attitude of valuing ‘my time’ while neglecting ‘other people’s time.’
Every time you do that, you have to realize that you are wasting the other person's time and losing their trust.
Consideration for time soon leads to trust.
In other words, if you work with the mindset of 'for you', your sincerity will be returned in the form of cooperation several times over.
This is the core of the 'FOR YOU work method' that will be introduced from now on.

If you ask people when they truly feel joy, surprisingly many will answer, “I don’t know.”
People who don't know what makes them truly happy can't have the best recharge time just for themselves.
Because no matter what I do, it's not fun.
A person who does not know my joy does not have an 'antenna of joy' set up.
Even if you are someone who feels that 'every day is not fun', if you carefully observe the movements of your heart every day, you will definitely find moments of excitement and joy.
You can't miss that moment.
It is important to realize that ‘I am really happy when I do ○○.’
(...) Life is to be enjoyed.
So, we must raise our antenna of joy with all our might.
There are bound to be moments in our daily lives that we find enjoyable.
If you encounter such a moment, be sure to write it down before you forget it.
