Many traders enter the market with a hidden goal.

On the surface, it's to make money.
In reality, it's to prove that they are right.
So every trade gradually becomes a kind of "judgment test."
When the price rises as expected, you feel a sense of satisfaction:
"I knew I was right."
But when the market moves against you, things start to get complicated.
You subconsciously do three things:
Explain the market,
Find reasons,
Keep waiting.
Because once you cut your loss, it means admitting:
You were wrong this time.
The human brain is naturally averse to admitting mistakes.
There is a classic phenomenon in psychology:
When people have already invested time, effort, or money, it becomes harder to give up.
This is called the Sunk Cost Fallacy.
The same applies in trading.
Once you've opened a position and are at a loss, your brain keeps telling you:
"Wait a little longer."
"The trend hasn't changed."
"It will rebound soon."
These sound like analysis, but they are just another form of self-protection.
Because as long as you haven't cut your loss, you haven't "been wrong."
Thus, trading begins to distort gradually.
Originally:
Judgment → Trade
Later becoming:
Judgment → Prove Judgment
When the goal of trading becomes "proving oneself," the risk increases exponentially.
Because you stop caring about the market.
You only care about one thing:
"Am I right?"
This is where the market is the cruelest.
It doesn't care whether you're right or not.
The market only cares about two things:
Probability
and
Risk.
You can be correct in your judgment, but if your position size is too large, a single retracement can wipe out your account.
