Good article - it covered a lot of the topics, from the win loss ratio, to options selling to the inbuilt feel good.
I have always found it interesting that professional money managers as well as the retail investors fall for this.

The old Bernie Madoff type returns of lots of wins means its a good system - until you loose all your money. (While there were more corrupt reasons for Bernie, the fact remains he got away with it for so long as people fell for that return profile)

didn't one of the original market wizards say it all perfectly when they mentioned something about the importance in the magnitude of the wins vs the losses that is important.
