Changing how you feel and react to market moves & trades takes time. We might want to 'fix' our propensity to break the rules and go on tilt immediately. This can cause us massive frustration when we don't.

"Why can't i stick to my trading rules?"

"Why do I seem unable to control my impulse to trade?"

Know that it takes time, just like conditioning your body to the cold. The first few times you do it, you can't control your response, but over time you can teach yourself how to respond.
