Mccube,
The best traders measure themselves by long term, whole portfolio perfromance The ones who talk about one or two big winners are either trying impress a potential mate or have conviently forgotten the loses.

The best poker players LOVE playing the guy who talks about the one huge win: just take half his money nine times, then let him double it once. He will keep coming back for more.

Good investors, whether in stocks or cards, remember each loss VIVIDLY and try to learn from the mistakes
