I saw a very correct passage on Douyin: A wave of market, a transaction, whether successful or not, in your long career, millions of transactions are like a drop in the ocean. Don't flutter for a success, and don't be upset about a failure. A peaceful heart is always the strongest weapon of professional traders, when you become impatient, blind, fearful, and anxious because of changes in the market and assets, whether you make or lose, you have already lost, and the wave of the market will infinitely amplify your emotions, make you exhausted, and give you a fatal blow.
