A single market movement, a single trade—regardless of success or failure—is just a drop in the ocean among the millions of trades you’ll make over your long career. Don’t get carried away by one success, and don’t be overly frustrated by one failure.

A calm mind is always the strongest weapon of a professional trader. When you become impatient, impulsive, fearful, or anxious due to market and asset fluctuations—whether you profit or lose—you’ve already lost. The tides of the market will amplify your emotions infinitely, and after exhausting you, deliver a fatal blow.
