True mature traders all have a "letting go" ability.

Many people fail at trading,
not because they can't analyze,
but because they always want to control the outcome.

They want to know in advance whether it will go up,
want to ensure they're right this time,
want the losses to come back quickly, want to make a little more profit.
But the market's worst match is precisely this kind of obsession.

Later, I gradually understood:
Trading is not about prediction, but about execution.
It's not about guessing the future,
but about doing what the market does according to the rules.
What if it goes up? What if it goes down?
If wrong, how to exit? If right, how to take profits?
This is what trading should really be about.

Many losses are not because of wrong direction.
But because you can't bear to cut losses,
can't forget the cost, always thinking "it will come back if I wait a little longer."
But the market doesn't know your cost at all,
and doesn't care whether you're unwilling to accept it.

If you make decisions based on your cost,
you're essentially trading with your emotions.
Truly mature traders may not be right every time,
but they usually do one thing right:
they don't fight the market,
they don't fight the cost,
they don't fight their emotions.
Cut losses when needed,
wait when necessary,
give up opportunities when it's time.

Because they know:
Trading is not about proving yourself, but about doing what benefits you in the long run.
