Perhaps the reason people are failing in trading is not because they have no discipline. It is simply they do not possess any edge. Once you have found the edge, it takes little discipline to follow it as you are winning more than losing. Many of the FF gurus are talking about the psychological stuff the traders need to cultivate in order to succeed. They simply do not know what they are talking about. What I said may sound harsh,but it is the truth. And knowing the truth will set you free, and put you in the journey to rediscover and learn how to trade. To be successful in this business, find a real and true edge. After which, trading is simply enter and exit. That's all ever to it.
Make everything as simple as possible, but not simpler.
