The toughest maxim for me to assimilate, at an emotional level is: The market is always right, and I am always wrong. When I am in a trade the market cares little for my expectations for the trade, as the market is essentially a function of the combined psychology of millions of traders, not the psychology of my trading, and when I am on the wrong side of a trade I am, quite simply, wrong. That is, indeed, a tough pill to swallow.
