Real reason why people lose is their wishful thinking. If you know what you are doing and have the discipline to follow your ideas, you have a good chance of coming out ahead provided of course you started off with a reasonable "backpack" of knowledge. This knowledge is not hard to come by. There is a bibliography and free charting packages that are of excellent quality - for which we had to spend a fortune 15 years ago. The extra element that has to be provided by the "would be millionaires" is aptitude. Fx is not for everybody but even those not "talented" enough can learn to make money if they just go over the trades that are going wrong and examine the reasons why they were put in the market in the first place. If the reaoning seems to be doubtful, get out of it! But if one keeps HOPING that it will finally come right, then.. disaster is waiting for them. For the market may turn but not before blasting these wishful dreamers. A Simple matter of stop loss placement wether it is dollar-stop or "so many pips against me and I am wrong" type of self-assessment, can prevent A/C-busting. The idea is to survive to fight another day ! This is all the discipline one requires to make money in this business.
Lastly, Please AVOID the Psycho-books. They who can do. Failed traders and those who can not, write books, the worst of which are of the Psycho-variety. There are of course a number of books that are real good but the psycho-variety are not in this category. Re-engineering is NOT required if the engineering was done right in the first place. So, if your system is right, it will make money for you. If your system is wrong, no amount of psycho-stuff will work.
Wish you all Pips and Profits !
