A single market move, a single trade—whether successful or not—is but a drop in the ocean among the millions of trades you’ll make over your long career. Don’t become arrogant because of one win, nor despair because of one loss. A calm mind is always the trader’s greatest weapon. When market movements and asset fluctuations cause you to become impatient, reckless, fearful, or anxious, you’ve already lost—whether you’re profiting or losing. The market’s tide will amplify your emotions until they exhaust you, then deliver a fatal blow.
