The Box

 2020/12/20.  The Box


I am reading the book “The Box: How the Shipping Container Made the World Smaller and the World Economy Bigger.”.


Shifting Low productive works to be higher has a lot of stories.

This shifting is happening in lots places.

In Japan, for example, restaurants install tablet devices instead of hiring waiters.


I wrote below formula in post blog post.


P = ( S - C ) / T


P: Productivity

S: Sale

C: Cost

T: Time


If we want to improve productivity, we reduce cost and/or time.

Cost includes labor costs.

Labor cost is generally proportional to working time.

New technology makes less working time possible.

Then labors lose incomes.


This shifting is like how knowledge is treated in our brains.

If we know something, it is difficult to act as not knowing it.

This shifting is irreversible.


I think that this shifting is happening to everybody.

For example, I am learning Python on Udemy (Online Course).

This means I don’t need to go to school for it.

Reducing my time and cost for learning Python is done by online course.

I imagine that how others do when they want to learn Python.


Do they learn Python as same as I am learning?

I feel that most adult Japanese can’t do it.

Because they can’t learn something new with English. 

Learning with English sounds difficult for most Japanese.

This is real.


The problem is shifting low productive works to be higher happens in Japan slowly or not.

Corona virus makes the shifting faster.

Corona virus reveals the difference between self-learning person and others.

The difference will be bigger and it is still invisible to others now.

Corona virus makes good chances to self-learning person.

Communication difficulties

Like or not like , comfort or not comfort... No. I read this answer by book. There are 5 patterns about relationships with others. Positive & Active people  Positive & Passive people  Negative & Active people  Negative & Passive people  Center & Neutral people  If other people's reaction is positive & active on communication , I am in negative & passive position. And if some people gets angry on brain imaging , they are negative & active people for me. And they see me as positive & passive people. Emotional stress is happened from the misunderstanding how others see me. Misunderstanding is happened between how I see myself and how others see me. So improving emotional reaction is to know how ot...

(1)They were telling about FX or stock automatic investment tools. ->A lot of people are trying it with very efforts.

(3)The solicitor told that this tools would bring money forever. ->100% scam. —>The result from (1)(2)(3), I thought that the scam is happened when there is information difference. Thinking about solicitation, we have to rethink if we are hunter or food.

Own view to World and I

  Own view to World and I I thought about feeling method about world and I. The principle questions are “What is the World?”, “Who am I?”. There are several feelings about these questions’ answers. View to World and I I am [ positive ] I am [ normal ] I am [ negative ] World is [ positive ] Normal A Mismatch B1 Mismatch C World is [ normal ] Positive thinking Normal B Negative thinking World is [ negative ] Mismatch A Mismatch B2 Normal C I categorized the answers in above matrix. If “World is [negative]” and “I am [normal]” is the answer, Mismatch B2 is my position. Then if we want to change something, we should change view to the world or I.

Cheaper work

2016/12/29. Cheaper works: Hard competition makes expensive work cheaper. In Japan, there are some people who thinks there are a lot of workers, and they are exchangeable easily. This thought can't stand on human populations decreasing society. And in this society, the flow that provides products cheaper and cheaper cannot keep. Now, Japanese society is standing on that thought, and Japanese system hardly stands. This is by the patience of Japanese. When the breaking point of Japanese system comes, the counter of patience will keeps long time. And I think that communism never comes in Japan. Because Karl Marx doesn't think about human populations decreasing...
