“The most sustainable outcome has been a more holistic understanding of what it takes to be a good trader. You are asking people who have been at least moderately successful to change (to some degree) how they trade, which is of course the basis of their compensation. Most of them think they know what they’re doing already. Most of them also think it is all about the market; not them.
I was initially skeptical. Think of it as an investment in yourself – a call option, if you will. If it improves your performance even marginally, the upside will compound spectacularly over the course of a career.”
