A normal mind can make people not arrogant or impatient when they make a profit, and not discouraged or depressed when they lose money. For example, a trader who is new to the market has good luck and makes a lot of profits at the beginning, but because he loses his normal mind, he blindly increases his position and eventually suffers heavy losses when the market reverses. Only by keeping a normal mind can we look at the ups and downs of the market rationally.

Greed often puts people in trouble. There was a trader who was driven by greed to increase his position when the market was rising, regardless of potential risks. As a result, he lost all his profits and suffered serious losses after the market correction. Only by learning to control greed can we avoid excessive risks.

It takes courage to face fear. Novice traders are often shrouded in fear after losses, and dare not make any more moves, missing good opportunities. Experienced traders will make rational decisions based on plans and strategies. For example, a senior trader does not retreat in the face of fear and takes decisive actions under controllable risks.
