During the Spring and Autumn period, Duke Mu of Qin asked Jian Shuo, 'How can I dominate the world?'

Jian Shuo replied: "To dominate the world, one must adhere to three cautions: do not be greedy, do not be angry, do not be hasty. Greed leads to greater losses, anger brings more difficulties, and haste causes many failures. When weighing the pros and cons and planning accordingly, why need greed? When comparing oneself to others and thinking from their perspective, why need to get angry? When considering the urgency of matters and planning calmly, why need haste? If you can heed these three cautions, you will be close to domination. ​"

The meaning is:

"Those who dominate the world have three cautions: caution against greed, caution against anger, caution against haste.

Greed leads to greater losses;

Anger easily brings difficulties;

Haste can cause missteps.

Weighing the pros and cons in planning, why need greed?

Empathizing with others, measuring oneself against others, why need to get angry?

Considering the urgency of matters and planning calmly, why need haste?

If you can adhere to these three cautions, your path to dominance will be nearer.

"

Think about trading as well, it is nothing more than:

Judging win rates/profits and losses, rather than blindly betting due to FOMO;

Controlling emotions, not losing rationality during wins and losses;

Not being hasty, but maintaining patience.

Two thousand years ago, Jian Shuo understood this; in modern times, he would also be a good trader.
