Need video interpretation of the following content, please pay more attention, and later share some of my insights without criticism. Essence of Trading Principles: A wave of market trends, a single trade, regardless of success or failure, is just a drop in the ocean of your long career with over a million trades. Don't be carried away by a single success, and don't be overly frustrated by a single failure. A tranquil heart is always the strongest weapon of a professional trader. When you become impatient, blind, fearful, and anxious due to market and asset changes, whether you gain or lose, you have already lost. The waves of the market will infinitely amplify your emotions, leaving you exhausted before delivering a fatal blow.
