“The market is never wrong in what it does; it just is. Therefore, you as an individual trader interacting with the market—first as an observer to perceive opportunity, then as a participant executing a trade, contributing to the overall market behavior—have to confront an environment where only you can be wrong, and it’s never the other way around. As a trader, you have to decide what is more important—being right or making money—because the two are not always compatible or consistent with one another.”

Mark Douglas, in The Disciplined Trader
