You shouldn't assume things like this. I read this book after 18 years of trading and the only regret I had was that I didn't read it sooner. This book inspired me to take a close look at my psychological makeup and examine my strengths and weaknesses. It's important to point out that I already had the skill but this book took my trading to a whole new level. There are many ways to achieve the ultimate goal. This just so happened to fit into a groove on the path I was traveling down. I've also read books on spirituality that have absolutely nothing to do with trading but improved my trading immensely. Everyone has to find their own groove and find the path that leads to that groove. No two traders are alike.
