One point that is particularly felt in the growth of long-term trading is,

Everyone must have heard it many times in different ways, similar to
"Trading goes against human nature; it requires overcoming oneself and defeating oneself, as the opponent is actually oneself."
In this case, it would definitely feel a bit like "grand principles."
Or it's too abstract, "Hmm, that makes sense, but it seems useless?"
How do you overcome and conquer yourself? Is it like being an ascetic?
There is a lack of reference standards.

I provide a perspective that may help to understand the logical principles and reference standards of this "reason" in a more concrete way:
Trading competition is a strategic competition determined by reflexivity, characterized by a boundary between winning and losing, as well as key points of examination.
In other words, as everyone understands, you have to defeat 80% or 90% of the people to achieve a victorious outcome.

This is like the college entrance examination; the admission score line is different every year.
If 1 million candidates, 200,000 are admitted to first-tier universities,
So the admission score line is the exam score of the 200,000th ranked person.
It is a type of performance leaderboard that looks at relative performance,
It does resemble a game of musical chairs, where the number of winning seats is fixed.

But the difficulty of the college entrance examination papers and test papers is designed by the teachers of the question-setting group.
The questions and difficulty of the trading arena are designed by all participants themselves.

For example, if most people are in the state of "I know X,"
So the standard for the boundary between victory and defeat, or the focus of the exam questions, is "I know you know X."
If most people are in a state of "I know you know X,"
The boundary between victory and defeat becomes "I know you know I know X".
...

Without training for this competitive activity of trading,
Although everyone has a different level of understanding of the "technology" and "knowledge" related to trading,
The difference limit can be quite large.
Because this part is closely related to experiences and education in the future, such as a person's financial knowledge, logical thinking, the ability to understand and comprehend things, and understanding the fundamentals of the assets, among other things.

But everyone's human nature and psychological behavior patterns related to transactions,
The natural differences are much smaller compared to the former.
Because everyone has grown up in the normal real world.
It did not grow up in the world of virtual reflexive strategy competition rules.
Parents and schools don't teach these things, and educational qualifications have little impact on this.
(Playing Texas Hold'em poker and esports for a long time will teach people something, but there will still be differences.)
For example, a college graduate and a person with 5 to 10 years of work experience in a top-tier 985 company,
Or say a regular employee of a large factory and the owner of that large factory,
Let them all start trading, using a similar "funds占自己资产比值" to run.
Their results are similar, as the issues exposed by the lack of experience in this area are basically the same, showing similar performances.

This is why,
For example, a "big shot" who understands BTC better.
and an ordinary person who doesn't really understand BTC,
If you use half of your fortune to trade BTC,
Especially in the case of high frequency and high leverage,
There can be many similarities in the reasons for making mistakes.

"What my physiological first reaction is, is also what others' physiological first reaction is."

So the conclusion:
In trading, related to human nature and psychological behavior patterns,
One's nature is similar to that of others.
So
Knowing yourself ≈ Knowing others
(The source logic of value in introspection)
Overcoming oneself ≈ Overcoming others
(By defeating one's own nature, one naturally defeats most others, which is the opponent's strategy.)

From this perspective,
"Overcoming human nature, defeating oneself, the opponent is actually oneself" these words,
It may seem less profound and abstract.
Is it easier to have standards for seeking a steed?
