Yesterday, I introduced my study method.

However, it may be necessary to consider whether such techniques and language study methods are worth the cost (cost and time).

You don't have to study on your own if you can keep a specialist of foreign languages and specific skills .

But in most cases, keeping such talent is terribly difficult.

Employment costs for such people are high and competing.

There are even companies that do "order fictitious work" just to keep the human resources.

-----

On the other hand,

"It's bothersome and time-consuming to study language and skills on my own."

is reasonable.

This is a comparison between

"The cost of studying and acquiring skills"

and

"The cost of keeping people who have alreay studied and acquired skills"

And choosing the one with the lowest cost is a market principle.

-----

But we have to think one more upper step. That is

"I who am studying and acquiring skills"

or

"I who can keep people who have alreay studied and acquired skills"

The question is which one has market value.
