I went country home for 12 hours. If I encountered a traffic jam as early as 6 hours by car.

The cost is going to be more expensive that using the Shinkansen for four people of my family.

However, the family lifestyle continues to change.

One is for an internship, one is for a trip, one is for going country home, and I am also going counter home again.

With one, two, three and four people, the state transitions from intensive behavior to autonomous decentralization. In the future, the number of members will decrease, and eventually I will be the last. Or, I think that I will disappear without waiting for that number.

From a macroscopic point of view, my life is as simple as stepping the template flow one by one.

However, from a microscopic point of view, I always feel that it was just what was expected above.

The wisdom and know-how of the ancestors were almost never useless for my case.

When enough time has passed after the event is over, it is just an illusion that the wisdom and know-how of the ancestors were hit.

However, I think it is important to “imitate” the wisdom and know-how of our predecessors.

Life is too short to repeat trial and error.

"There is no way in front of me. A road appears behind me". This is one phrase of famous peom in Japan.

When I read this poem for the first time, I thought, "This person (poet) is a pessimist who cannot calculate the cost"(*).

(*) This time, I read the full text of 102 lines.

To be clear, it is inefficient.

For me, I will write,

"Walking the road in front of me, I reach the destination with the lowest road construction cost when needed. I will collect usage fees for the roads behind me"

(By the way, this is the basic idea of patent law in all countries).
