I was just skimming through one of my Trader Vic books last night and read this again. I think this is an excellent analogy to why so many traders fail... The question is... "Why do so many traders fail?" "The difference is neither intelligence nor knowledge, but the will to execute knowledge. Acquiring the requisite knowledge to trade, or to do most things in life, is relatively easy. For example, consider the area of weight loss. You can walk into any bookstore and find countless books on the subject by experts who outline proven and healthy weight loss techniques. Yet, only 12 in 100 people who start a weight loss program actually lose weight, and only 2 of those 12 maintain the loss for more than one year. That's a 2% success rate...worse than the 5% success rate for commodity trading! Whether it's trading, losing weight, or pursuing any other goal, the most difficult part isn't in knowing what to do or how; it is in making the decision to do it and stick to it."
