True wealthy individuals deeply understand the principle of going with the flow: they strive hard during good times and know when to withdraw during downturns. They act low-key and are humble, understanding the cyclical nature of prosperity and decline.

There was once a client worth several billion who went bankrupt overnight due to the financial crisis, yet remained remarkably calm.

In response to others' comfort, he instead reassured everyone: "Fortune and misfortune are hard to predict, experience and family remain, and my son can inherit everything in the future."

This calmness demonstrates the power of emotional stability—only by not forcing against the flow can one calmly face the ups and downs of life.
