《The Minato Family's Diary of Blunders》 Episode 7: The Day My Heart Dried Up from Too Much Frugality — The Psychology of Cactus Household Finances —

"Hey, don't you think it's been kind of quiet in the house lately?"
My wife said that while looking at the electricity bill.
It was true; lately, we'd been turning the TV off more often, and the heater was set to a bare-minimum 18 degrees Celsius.
We changed our bathing habits to "everyone taking a quick bath in succession to avoid waste" and our laundry to "doing it all at once twice a week."
—Yes, our household had entered "frugality mode."

It all started with an electricity bill notification on my phone.
The moment I saw the words "+1,280 yen compared to last month," a switch flipped in my heart.
"This is bad! We have to tighten our belts!"
And so, as if a Sengoku-period warlord charging into enemy lines, I marched out onto the front lines of frugality.

I'd open the fridge and say, "No leaving it open!"
If the tap was running, I'd point it out, saying, "How many liters is that one second costing us!?"
I put a sign on the air conditioner remote saying "Strictly 28°C," and
I hung a "No Luxury Allowed" tag on the potato chips in the snack corner.

—Yes, I had completely turned into a "cheapskate."

■ The Birth of Cactus Household Finances.

Then one day, my wife muttered to herself,
"You know... my heart feels all dried up."

That one sentence made me jump.
I realized that the air in our house was as dry as a desert.

"Cactus Household Finances"—.
In positive psychology, there is a phenomenon called this.
It is a state where you use only the minimum energy necessary to survive,
and cut off the water known as "enjoyment" yourself.

For example,
・Enduring the urge to buy coffee because it's a waste of money
・Not buying snacks for the kids and saying, "Let's just make do with what we have at home"
・Canceling weekend outings because "gas money costs too much"
—As a result, your heart loses its moisture.

Frugality itself is not bad.
In fact, there are many studies in psychology that show "people who can save money have higher levels of happiness."
However, when saving becomes the goal, people only focus on the "lack."
They fall into the illusion that "if I endure more, things will get better."

—

■ Where Did the "Happiness Savings" Go?

Our house was in exactly that state.
The living room with the lights off was as dim as a night at a campsite,
and the children were watching YouTube in hushed voices.
Snack time had also disappeared, replaced by "bean sprout snacks (stir-fried bean sprouts with salt)."
…The fact that this was surprisingly delicious was, conversely, sad.

At that moment, my second son muttered,
"Hey Dad, why don't we buy ice cream anymore?"
Reflected in the depths of his eyes was a young heart that had begun to accept "endurance = the norm."
Frugality is supposed to be a **"means to protect something,"**
but before I knew it, it had become a "rule that cuts away at happiness."

What psychologists call "narrowing of focus" was occurring.
In other words, a phenomenon where your consciousness is so focused on frugality that you lose sight of the overall balance of happiness.
You can "save money," but you cannot "save your heart."
I was slow to realize that difference.

■ The "Emptiness" Beyond Frugality

One night, after a bath, I stood frozen in front of the refrigerator.
In the kitchen, where the lights were off to save electricity, I thought while pouring barley tea in the dark,
"Somehow, there's no sense of accomplishment."

The utility bills had certainly gone down.
Beautiful numbers like "-15% in expenses" lined up in the household account book.
But next to them was a silence that felt like the number of smiles had decreased.
In exchange for the success of frugality, the sound of my family's laughter had faded.

In positive psychology, there is a concept called the **"Hedonic Budget."**
It is a theory that to maintain long-term happiness in life, one should distribute both "pleasure" and "savings" in a balanced way.
If you "cut everything," your brain falls into a state of "reward deficiency,"
your motivation drops, and as a result, you experience a rebound of wasteful spending.

In fact, that was the case for our family too.
The following month, as a "reaction to the endurance," I clicked to buy a humidifier and high-end coffee beans online.
My wife bought a heated carpet, saying, "It's a reward for saving electricity!"
Before I knew it, we had easily exceeded the amount we had saved.

■ The "Courage to Spend" Is Also Wisdom.

That night, I told my wife honestly,
"I'm sorry, we were a bit too frugal."
My wife laughed and replied,
"Yeah. But you know, this wasn't all bad. I learned something."

—Yes, after going through "Cactus Household Finances,"
we learned the "perfect humidity for money and the heart."

The moment you forget **"what you are doing this for,"** both frugality and investment go off track.
Choosing expenses that nourish the heart is far more constructive than frugality that dries it out.
Revisiting that balance is the true maintenance of household finances.

The next day, we went to eat ice cream with the kids.
"Let's splurge a little today!"
Even though it was just 300-yen ice cream, our happiness levels soared.
I felt that the children's smiles were far more important than the numbers in our household budget.

The "Courage to Spend" to Regain Happiness — The Psychology of Cactus Household Finances

The frugality boom.
Social media is filled with the fruits of effort and wisdom, such as "Living on 20,000 yen a month for food" and "Zero electricity bill challenge."
But behind those posts, how many people are cutting away at their own hearts?

I used to be like that too.
A time when I thought, "The less I spend, the more I win."
However, from a psychological perspective, that was not a "win," but the result of "defense."
This time, let's think about that mechanism and how to escape it together.

—

■ 1. Cactus Household Finances is a phenomenon of "protecting happiness so much that you wither it"

In positive psychology, human happiness is explained by two axes: "pleasure" and "meaning."
Among these, people who fall into "Cactus Household Finances" have a strong tendency to cut the "pleasure element" themselves.

Example:
• Enduring not traveling and telling yourself, "I can go sometime later"
• Reducing cafes and eating out and feeling relieved that "I saved money"
• Refraining from gifts and eating out and feeling satisfied that "I didn't waste money"

At first glance, it seems positive, but the brain is feeling "reward deficiency."
It is what is called a "dopamine depletion state" in psychology.
When pleasure chemicals decrease, motivation and creativity also drop.
Even if the frugality continues, the sense of happiness does not.

Interestingly, in research by Canadian psychologist Martin Ford,
it is stated that "the more people continue to be frugal, the higher the probability of 'rebound spending' after a certain period."
The reason is simple. The brain seeks a "reward" and breaks through your willpower.

In other words, in a state of emotional dryness, the sustainability of frugality also drops.
Even if a cactus can endure without water, it cannot bloom forever.

—

■ 2. The moment frugality becomes a "defensive behavior"

The reason I got so obsessed with frugality was also triggered by anxiety.
Rising electricity costs, children's education expenses, the 20-million-yen retirement problem...
All of them have "worry" at their roots.
And anxiety prompts us to take "defensive actions."

What is called **"Defensive Economic Behavior"** in psychology.
・Increasing savings just to avoid risk
・Gaining peace of mind by suppressing expenses
・Sacrificing current happiness in the name of "for the future"

These seem rational at first glance, but they are actually just "controlling anxiety."
You are canceling out "future anxiety" with "current endurance."
And that repetition creates a mislearning that "enduring = peace of mind."

■ 3. Three psychological biases that create Cactus Household Finances

So, why do people dry out their own hearts?
In the background, there are three representative psychological biases.

① Scarcity Mindset

The moment people feel they "don't have enough," their field of vision narrows.
In research by Mullainathan and Shafir,
it is stated that "people who feel a lack of money have their IQ drop by 10 points."
In other words, when you get obsessed with frugality, your judgment itself becomes dull.

② Illusion of Control

You convince yourself that "if I don't spend, the future will be stable," and
by reducing expenses, you get the feeling that you can "manipulate the future."
In reality, uncertainty does not decrease.
But you want the "feeling of doing something."
This becomes the psychological fuel that tightens the household budget more than necessary.

③ Guilt Bias

The imprint that "wasteful spending = evil."
The more people were told as children to "take care of money,"
the more likely they are to feel guilt about "spending it."
However, money is energy that exists to be used.
If you stop it too much, the flow will stagnate.

■ 4. "Pleasure spending" that moistens the heart — Happiness budget viewed from PERMA theory

Dr. Seligman, a leading expert in positive psychology,
explained the five elements that constitute happiness with the PERMA model.

Element Content Application example in household finances
P Positive Emotion Small luxuries, cafe time, supporting your favorites
E Engagement Hobby tools, investment in learning
R Relationships Birthday presents, family trips
M Meaning Donations, education expenses, self-investment
A Accomplishment Visualization of household management, target savings

Frugal people tend to cut P (Pleasure) and R (Relationships).
However, these two are the expenses most directly linked to happiness levels.
In other words, the "courage to spend" is the key to maintaining the balance of happiness.

■ 5. "Pleasure spending exercise" — 3 steps to moisten your household finances

Step 1: Write down 3 "pleasures" you have been denying yourself recently.

Example:
・Reading at a cafe
・Eating out with the family
・Going to the movies once a month

Step 2: Think about "What did I gain by stopping those things?"

・I saved money
・I felt a sense of security
・But, I feel a little lonely

This "gain-loss memo" is the starting point for regaining balance.

Step 3: Calculate your "ROI (Return on Inspiration)".

Rate how much your heart was nourished by the money you spent on a scale of 1 to 10.
Spending that brings high satisfaction is "happiness spending."
Judge it by "resilience" rather than the amount.

⸻

■ 6. Sharing "pleasure" increases the happiness efficiency of your household budget

What's interesting is that even with the same 1,000 yen, the happiness effect differs depending on whether you use it alone or with your family.
According to social psychology research,
"Shared Spending" generates about 1.5 times the happiness of individual spending.
The reason is that emotions "resonate."

For example, sharing convenience store sweets with your family.
In this moment, oxytocin is released in the brain.
You gain "security," "connection," and "satisfaction" all at once.
Happiness resides in "sharing" rather than saving.

⸻

■ 7. Psychological training to reset your "frugality brain"

Try creating a "small luxury day" once a week.
Even 100 yen is fine.
On that day only, consciously spend money that "nourishes your feelings."

Then, at night, write it down in your notebook or smartphone.

What was nourished by today's money?

This record will help you relearn the link between happiness and spending.
From the perspective of behavioral therapy, this is called "Reward Relearning."
It has the effect of rewriting the "restraint circuit" related to money into a "pleasure circuit."

⸻

■ 8. Let's try it at a family meeting: "Nourishment Budget Meeting"

In the Minato family, after escaping the cactus household,
we changed our "frugality meeting" into a "nourishment budget meeting."

The method is simple.
① The whole family proposes ways to spend 1,000 yen
② Vote on "which one seems like it will nourish our hearts the most"
③ Execute it and share your impressions

For example, in our home,
Eldest son: "4 ice creams from the convenience store!"
Second son: "A new set of paints!"
Wife: "A slightly expensive bath salt"
Me: "Coffee beans and music"

As a result, it was unanimously decided to be "bath salts."
Seeing the smiles on my family's faces after the bath,
I felt that "this 1,000 yen was the best investment."

Psychologically, the "Joint Decision Effect" is at work.
When the family decides how to spend money, satisfaction increases and regrets about waste decrease.

⸻

■ 9. The "courage to spend" improves the circulation of life

Frugality is also an act of pausing the circulation of life.
It is good to rest when necessary.
However, if you keep it stopped, the circulation stagnates.

Happiness resides in the "flow."
Spend money → Receive gratitude → Become someone's income → Society is nourished
This chain fosters the feeling of being alive.
"Too much frugality" is an act of stopping this flow yourself.

⸻

■ 10. Finally — A habit to measure "heart humidity"

This is an era where both savings and investments are decided by the balance of "emotions," not numbers.
That is why I want to convey this at the end.

I want you to try recording not just "expenditures" but also "heart humidity" in your household account book.

Is today's self feeling dry?
Or is it a little nourished?
If you are dry, that is a sign of too much frugality.

⸻

💡Summary: 5 tips to escape the cactus household
1. Frugality is not the goal, but a means to happiness.
2. Do not feel guilty about spending.
3. Be conscious of the balance between "pleasure" and "meaning."
4. Spending shared with family has high happiness efficiency.
5. Cultivate the sensitivity to feel the humidity of your heart.

⸻

Those who are good at saving are actually also "good at managing happiness."
I think the courage to regain nourishment, rather than the strength to continue enduring, will be the new guideline for household budgets from now on.
