Pissing, moaning, whining and assorted other forms of bitching don't work either. In fact they are less effective than Technical Analysis, Daytrading, Fundamental Analysis, Black Boxes, Psychic Friends Network and assorted other methods.
Those are all by products of the realization that a trader is TOTALLY unprepared psychologically to trade and they have no current clue how to find a SOLUTION! Been there done that....LOL!
