Quote from harrytrader:
The greatest traders have began being losers. Even the great Jesse Livermore has been ruined at his beginning. Even Gann. Gann said in fact that losing motivated him. As for me I would never discover my model if I had not being washed exactly in the same circonstances as Jesse Livermore that is to say he didn't understand at first why after being so successful he suffered terrible losses. So you have to take some distance to understand why. Now of course not every losers will learn the lessons, so it will depend on people attitude and / or capacity to react to their losing situation.
Jess Livermore also died ruined (he shot himself). Gann also died without a penny.
