In Trading, the STATISTICS show that smarts, experience, etc. are not the differentiating factor.
The BEST (most successful guys I know and work with) have winning %’s of less than 50%.. actually, the average is between 45-55% but the point is, basically, winning percentages don’t matter – so they might as well be a random event.

 So, what does make a difference?  

• CONVICTION in ideas
• INTERNAL CONFIDENCE
• TRUSTING YOURSELF
• GETTING BIG IN TRADES you believe in
• LETTING WINNERS RUN
• CUTTING LOSERS QUICKLY
• SWITCHING DIRECTIONS QUICKLY

 These are many of the factors that allow some people to become monster traders over time. It’s not my opinion, just my observations.
