Trading should be done in a calm manner. The amateur traders show the true colours; whooping for joy when making a profit, swearing at the market when losing, shouting out prices at any slight jump in the price.... That is a terrible way to live.

If you make money, pat yourself on the back and take the accolades, not boast by whooping out loud. When you make a loss, take responsibility and blame it on yourself, not the imaginary manipulator inside the trading screen...
