You always need to be mapping your trading methodology to the current market environment. If you're trading volatility breakouts and the market isn't volatile and you have 8 losing trades in a row, then it really is your fault for not having an effective counter-trend trading strategy or worse not recognizing the market for what it is and stepping aside. Or, you can choose to build up your intellectual capital and enhance your techniques while waiting for the market to come to you.
I wholeheartedly agree that for the most part, the psychological aspect is bull -- unless you simply can't pull the trigger. Then you've got real issues. There is a bubble in trading psychologists, coaches, and mentors.
But back to trading... I never accept a loss on its face value unless it's an overnight position with a gap that goes against me. Or some f'ing jackoff NASD bureaucrat who decides that trades over a specific 8-minute interval have to be cancelled and they steal your money.
Analyze, analyze, analyze.
Code, code, code.
Test, test, test.
Trade, trade, trade.
